Question 2 options:
Habitats of animals were respected as much as possible.
The area is becoming deforested.
The forest is managed sustainably.
The workers that cut down the trees were not paid.
The working conditions in the forest are safe.
The indigenous people of the forest were moved to a safe location.
Answer:
Habitats of animals were respected as much as possible.
The forest is managed sustainably.
The working conditions in the forest are safe.
Explanation:
The Forest Stewardship Council (FSC) is a non-profit organization that tends to promote sustainability of forests and protects the forest species by ensuring forest resources that are of social and economic values are explored in an environmental-friendly manner. So if a wood is FSC certified it means it came from a forest that is well preserved and where sustainable practices are being observed strictly.
Therefore, we can infer that an FSC certified wood most probably came from the following areas which connotes sustainability and preservation of the forest resources is pursued strictly to maximize its social and economic benefits and prevent deforestation and loss of habitats of animals:

A student says that ""ALL DNA codes for proteins."" Do you agree with her? Why or why not?
It is not true that all DNA codes for proteins, as only some amount of DNA is coding.
What is a protein coding gene?Protein coding sequences are DNA sequences that are transcribed into mRNA and then translated into a polypeptide chain by the corresponding mRNA molecules.
In a protein coding sequence, every three nucleotides, known as a codon, encodes one amino acid in the polypeptide chain.
Long non-coding sequences in eukaryotic DNA separate relatively infrequent gene islands.
When DNA is extracted from living cells, the proteins (including histones) are usually dissolved away. As a result, long strands of bare DNA are formed that retain their genetic information.
Only about 1% of DNA contains protein-coding genes; the remaining 99 percent is noncoding. Noncoding DNA does not contain protein-making instructions.
Thus, it can be concluded that all DNAs does not code for all proteins.

Final answer:
All DNA does not code for proteins; genes within DNA do code for specific proteins, but there are regions of DNA with regulatory, structural, or other non-coding roles, and only certain genes are expressed in specific cell types for protein synthesis.
Explanation:
While it is true that DNA contains the instructions for protein synthesis, it is not accurate to say that all DNA codes for proteins. There are segments of DNA that play regulatory, structural, or other roles within the genome that do not code for proteins. For instance, only specific genes are expressed in a given cell type, which means that only certain portions of DNA are activated and used to make proteins that the cell needs. Moreover, the process of gene expression and protein synthesis, which includes transcription and translation, involves using the information encoded by genes to create proteins.
The Central Dogma of Molecular Biology explains that DNA is used to create RNA, which then serves as a template to synthesize proteins. Each gene, a segment of DNA, carries the code for a specific protein and through the genetic code, which is universal across nearly all species, the sequence of DNA bases is interpreted to produce the required proteins. However, not all DNA segments are involved in coding for proteins. Some DNA sequences regulate gene expression, some are involved in structural configurations, and yet others remain as non-coding regions with varied functions within the organism's genome. Therefore, it is a simplification to assert that all DNA codes for proteins.

Explanation:
Solar energy: Advantages: Solar energy is pollution free and causes no greenhouse gases to be emitted after installation. Disadvantages: Although solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops.
Wind energy: Advantages: It doesn't pollute air like power plant relying on combustion of fossil fuel. Disadvantages: Wind turbines can be a threat to wildlife (e.g. birds, bats).
Hydroelectric energy: Advantages: Hydroelectric energy is fueled by water, so it's a clean fuel source, meaning it won't pollute the air like power plants that burn fossil fuels, such as coal or natural gas. Disadvantages: Electricity generation and energy prices are directly related to how much water is available. A drought could potentially affect this.
A plant with two dominant OR two recessive alleles is said to be
True breeding
Cross pollinating
Homozygous
Heterozygous
Answer:
Homozygous
Explanation:
Homo - Same/ zygous - same alleles
Final answer:
A plant with two dominant or two recessive alleles is said to be homozygous, meaning it has two identical alleles for a specific gene, leading to the organism breeding true for that trait. This genetic characteristic is central to Mendelian genetics and contrasts with being heterozygous, which involves having two different alleles for a gene.
Explanation:
A plant with two dominant or two recessive alleles is said to be homozygous. Homozygous organisms have two identical alleles for a given gene, which can be either dominant (e.g., YY) or recessive (e.g., yy). This genetic makeup leads to the organism breeding true for that trait, meaning if crossed with another homozygous organism for the same trait, the offspring will exhibit the same phenotype. For example, Gregor Mendel's experiments with pea plants showed that crossing two homozygous individuals (each with either two dominant or two recessive alleles) resulted in offspring that were also homozygous and displayed the characteristic phenotype of the dominant allele if present (YY or Yy), or of the recessive allele if two recessive alleles were present (yy).
Being homozygous differs significantly from being heterozygous, where an organism has two different alleles for a gene (e.g., Yy). In the case of traits that follow Mendelian inheritance patterns, such as the pea plants Mendel studied, a heterozygous organism will exhibit the phenotype of the dominant allele.

Which statements describe the energy in a food web? Select three options.
When an organism eats another organism, it loses energy.
O Producers have the greatest amount of available energy.
O Energy can follow many different paths.
When an organism eats another organism, it gains energy.
O Producers have the least amount of available energy.
Energy always follows a single path.
Answer:
Producers have the greatest amount of available energy,
Energy can follow many different paths.
When an organism eats another organism, it gains energy.
In a food web, energy transfers from one organism to another through consumption. Producers, like plants, have the highest energy levels as they produce energy directly from sunlight through photosynthesis. Unlike a simple food chain, a food web shows multiple paths of energy transfer.
Explanation:In a food web, energy is transferred from one organism to another through consumption. The correct statements that describe the energy in a food web include: 'When an organism eats another organism, it gains energy', 'Producers have the greatest amount of available energy', and 'Energy can follow many different paths'.
When a prey is eaten by a predator, the predator gains energy obtained from the food it has consumed. Next, in any ecological network, producers, such as plants, have the highest amount of energy available. This is because they generate energy directly from the sun through photosynthesis. Lastly, unlike a simple food chain where energy follows a single path, a food web shows that energy can travel through multiple paths as organisms can have multiple predators and prey.

It is likely that a member of the
Lepidoptera family seen flying durin
the day is
a. a butterfly
b. a moth.
a c. another kind of winged inscot
A member of the Lepidoptera family seen flying during the day is likely a butterfly.
Lepidoptera, which includes butterflies and moths, are easily identified by their two pairs of scaled wings, with the forewings larger than the hind wings. The general difference in behavior between the two is that moths are usually night-flying insects that are more cryptic or camouflaged within their habitats, whereas butterflies frequently fly during daylight hours and rely less on camouflage.
Butterflies are more visible than moths during the day because many butterflies pollinate flowers which are brightly colored, open during the day, and produce nectar specifically to attract daytime pollinators.
Moths, such as the Noctuidae family member like the corn earworm, tend to be active at night and are important pollinators for night-blooming plants, forming symbiotic relationships where the plant is pollinated while the moth feeds.

Which one of these is NOT an example using facilitated diffusion?
The release of red blood cells that can accept oxygen through diffusion is not an example of facilitated diffusion. Facilitated diffusion requires specific membrane receptors or channel proteins to aid in the movement of substances down their concentration gradient. This is not the case in the process of red blood cells accepting oxygen.
Explanation:The option: 'Releasing red blood cells that can accept oxygen using diffusion as opposed to facilitated passive transport' is NOT an example of facilitated diffusion. Facilitated diffusion is a type of passive transport that uses specific membrane receptors or channel proteins to move substances down their concentration gradient. Examples of facilitated diffusion include the movement of glucose, amino acids, and in certain situations, Na+ ions. However, the release of red blood cells accepting oxygen is a process that isn't facilitated by any carrier or channel proteins, hence, it is not an example of facilitated diffusion.

what human activities prevent the artificial ecosystem of the city park from changing?
Explanation:
People running, cycling, and existing scares away animals
Breathing, exercise and planting of trees are the human activities which prevent changes in artificial park.
Human activities such as breathing, exercise and planting of trees prevent the artificial ecosystem of the city park from changing because these activities has good effect on the park not a bad effect. Breathing provides carbondioxide gas which is used by the plants as a raw material in making food during the process of photosynthesis.
Planting more trees and plants make the park more beautiful and full of organisms because plants provides food as well as habitat for thousands of organisms so we can conclude that breathing, exercise and planting of trees are the human activities which prevent changes in artificial park.

Using the genotypes and phenotypes provided from the iguana gene pool, which statement is NOT correct?
A) Webbed feet is the recessive trait.
B) WW x ww produces offspring with no webbing.
C) 2 iguanas with no webbing could have an offspring with webbing.
D) Crossing an iguana with webbed feet with one with no webbing would produce iguanas ALL with no webbing because this is the dominant trait.
Do you have the provided iguana gene pool?
Statement B is incorrect as crossing a homozygous dominant (WW) and a homozygous recessive (ww) iguana would produce all heterozygous (Ww) offspring with the dominant phenotype of no webbing.
In addressing which statement is NOT correct when considering iguana genotypes and phenotypes, careful analysis of genetic principles is required.
Statement A suggests that webbed feet are recessive, which implies that ww would be the genotype for webbed feet. Statement B is incorrect because a cross of WW (no webbing) with ww (webbed feet) according to Mendelian genetics would produce offspring with a Ww genotype, which would display the dominant trait of no webbing.
Statement C is possibly correct because two iguanas with no webbing could be heterozygous (Ww) and thus, could produce offspring with webbing if both pass on the recessive allele (w).
Statement D would produce offspring with webbed feet if the dominant trait was no webbing as the cross of a heterozygous dominant individual (Ww) with a homozygous recessive (ww) would result in half the offspring being heterozygous (Ww and phenotype of no webbing) and half being homozygous recessive (ww with webbing), not all with no webbing as the statement incorrectly suggests.
Name three invasive species and the specific location on Earth that they are affecting.
Answer:
Rats - Virgin Island
Hemlock - Asia
Zebra moulds - Great Lakes
Explanation:
An alien species is one that was introduced into a new environment, but does not have harmful effects. Such alien species are considered invasive species as they begin to have harmful effects on the new habitat. Invasive species can cause damage to the ecosystem, economic harm or human health effects.
Three invasive species are as following:
Rats that came on board ships to the Virgin Islands infested the islands' sugar cane fields and caused significant crop damage. The woolly adelgid hemlock is an invasive Asian insect which rapidly kills infested hemlock trees.

The “m” in mRNA stands for “messenger”. Is this an appropriate title for mRNA?
you can call it a Messenger RNA but it is more preferable if you write mRNA as there are other types of RNA such as tRNA transfer RNA
Yes, the title "messenger" is appropriate for mRNA because it carries genetic information from DNA to ribosomes for protein synthesis.
Explanation:Yes, the title "messenger" is appropriate for mRNA. mRNA stands for messenger RNA, which is a type of RNA that carries the genetic information from DNA to the ribosomes in the cytoplasm, where it acts as a template for protein synthesis. It serves as a messenger between the DNA in the nucleus and the protein-making machinery in the cytoplasm.
For example, when a cell needs to produce a specific protein, the DNA is first transcribed into mRNA. The mRNA then travels to the ribosomes, which read the instructions on the mRNA and build the protein accordingly. This process is often compared to a messenger carrying a message from one place to another, hence the name "messenger RNA".
The term messenger is appropriate because the mRNA molecule carries the genetic information from the nucleus, where the DNA is located, to the ribosomes, where proteins are synthesized.

Think about a person at the equator, a person at the North Pole, and a person somewhere in between. Each person points toward the sun. Describe where in the sky they are pointing.
The intensity of the energy received near the equator is higher than that at polar regions because the sun's light is less dispersed there.
What is an equator?A spheroid, like Earth, is divided into its northern and southern hemispheres by a circle of latitude known as the equator. It is a hypothetical line on Earth that is halfway between the North and South poles and is situated at 0 degrees latitude. Its circumference is 40,075 km.

Final answer:
Direction to the sun varies by location: At the equator, one points straight up for noon sun; at the North Pole, one points at the horizon if the sun is visible; and at intermediate latitudes, one points at an angle correlating to their latitude.
Explanation:
If a person at the equator, a person at the North Pole, and a person at an intermediate latitude each point toward the sun, they would be pointing in different directions in relation to their position on Earth. For a person at the equator, the sun would pass overhead along the celestial equator, reaching the zenith (the point directly above them). At any time of day, when they point to the sun, they would be pointing straight up when the sun is at its zenith, or towards the horizon at sunrise or sunset. During the equinoxes, the sun rises due east and sets due west for all observers on Earth.
At the North Pole, the north celestial pole is overhead, and during the summer months, the sun never sets, just circles around the horizon. So, when pointing to the sun from the North Pole, a person would be pointing to the horizon that surrounds them. During Winter, the sun would not be visible from the North Pole. At an intermediate latitude, the angle at which a person points to the sun depends on the latitude; it correlates with the altitude of the celestial pole above the horizon. The sun will travel across the sky at an angle to the horizon, rising in the east and setting in the west.
Describe the path taken by a carbon atom as it moves from being part of the carbon dioxide in the air to being part of a starch in a plant. (5Marks)
Answer:
Photosynthesis
Explanation:
1. Diffusion of CO2 into the leaves by stomata
2. CO2 reacts with water in presence of sunlight
3.Chlorophyll in chloroplast act as a catalyst
4.Photosynthesis takes place
5.Product contains glucose that is C6H12O6 and is converted to starch
Plants get the carbon dioxide they need from the air through their leaves. It moves by diffusion through small holes in the underside of the leaf called stomata. These let carbon dioxide reach the other cells in the leaf, and also let the oxygen produced in photosynthesis leave the leaf easily.
What is photosynthesis?Photosynthesis is a process that occurs in the chloroplast organelle of plant cells. The typical light reaction of photosynthesis takes place inside the thylakoid membrane of the chloroplast. The chief reactants such as water and carbon dioxide participate in the reaction. The water gets oxidized in the reaction to release oxygen as a product. The carbon dioxide gets reduced.

Skin prevents your body from losing water and helps it maintain its proper temperature. It also secretes the hormone calcidiol The skin belongs to the systems?
Answer:
Skin belongs to integumentary system.
Explanation:
Integumentary system is a type of system which consists of various elements such as skin, nails, exocrine gland and hairs. Skin is the largest organ in the human body. Skin has small pores which helps in regulation of body temperature by removing heat with water in the form of sweat through skin pores. It also provides protection to the body against pathogens such as bacteria and viruses etc.
The skin belongs to both the integumentary and endocrine systems.
The skin is primarily part of the integumentary system, which includes hair, nails, and glands. This system's main functions are to protect the body from environmental hazards, regulate body temperature, and prevent water loss.
Additionally, the skin plays a role in the endocrine system by secreting the hormone calcidiol, a precursor of calcitriol (active vitamin D). This hormone is crucial for calcium homeostasis and bone health.
By producing calcidiol, the skin contributes to the body's ability to maintain proper levels of calcium and phosphorus, thereby supporting overall metabolic functions.
