Where is RNA made? & Where does it go?

Answer: the answer is the second to last one

Explanation:

Answer:

The type of fossil can show what the terrain was like.

Explanation:

Fossils can give information about past environmental conditions by showing the type of animal they belonged to. If a scientist found a whale fossil in a desert, he/she could assume that the desert was once an ocean as whales only live in oceans. If someone found a fossil of a lizard that inhabited trees,  in the middle of the ocean, then he/she could assume that the ocean didn't exist at one point and instead, there might have been a forest in it's place.

Fossils inform us about past environmental conditions by providing evidence of ancient habitats and climates. Plant fossils can indicate previous warm and humid climates, while marine fossils suggest past sea levels and conditions. Fossil studies help reconstruct paleoenvironments, contributing to our understanding of Earth's history.

Fossils can provide a plethora of information about past environmental conditions. These preserved remains, such as bones, teeth, and impressions, serve as evidence of life that has long since vanished from our modern world. Through studying fossils, scientists can make inferences about ancient habitats, climates, and how organisms interacted with their surroundings.

Two examples that illustrate how fossils can reveal past environmental conditions are the study of plant fossils and marine fossils. Plant fossils, like those of ancient ferns, may indicate that a particular area was once a swamp or had a warm and humid environment. This is evidence of climate conditions in that area at the time the plant was alive. Another example is the study of marine fossils found in areas that are now deserts. Such discoveries suggest that the region was once underwater, revealing past sea levels and oceanic conditions. These fossils provide information on the temperature, salinity, and depth of the ancient seas, thereby informing us about the Earth's geological past.

Fossils give us the unique opportunity to reconstruct ancient ecosystems. Through them, paleoecologists may deduce paleoenvironmental conditions such as water depth, light availability, and energy level (calm vs. turbulent). For instance, the presence of oyster fossils can suggest that the area had the capability of supporting life that could withstand varying salinity levels, indicating that the water body experienced changes between fresh and saltwater influxes. This ability of reconstructing paleoenvironments is valuable not just for evolutionary biology but also for broader fields like geology and even climate science.

Answer:

Law of segregation is when two genes control the alleles and those two genes go to two different chromosomes. Law of independent assortment is when two genes control the alleles and are inherited independently.

Explanation:

Mendel’s laws in genetic terms, that is, in terms of chromosomes, genes, and alleles states that the genes activity along with the expressions that they express within the progeny.

It is defined as unit of inheritance that states that gene basically controls the expression of the character and pass on through chromosome.

Mendel's law of independent assortment states  that the chromosomes express themselves individually that the genes are expressed independently in the process of inheritance in the progeny.

Law of segregation says that the genes gets segregated before passing on to their progeny before expressing they assort independently and segregate as such in the progeny.

Mendel's law of segregation is the first division of meiosis in which the homologous chromosomes with their different versions of each gene are segregated into daughter nuclei.

The true statement about glycolysis is that it requires glucose as a reactant. Glycolysis is anaerobic and occurs in the cytoplasm, yielding two ATP molecules and not 36. It does not take place in the mitochondria nor require oxygen directly.

The true statement regarding glycolysis is that it requires glucose as a reactant. Glycolysis is a sequence of enzymatic reactions where glucose is converted into two molecules of pyruvate. This process is anaerobic, meaning it does not require oxygen, and it takes place in the cytoplasm of both prokaryotic and eukaryotic cells, not in the mitochondria. Therefore, statements B and C are incorrect. Statement D is also incorrect because glycolysis can occur whether oxygen is present or not, making it an anaerobic process. The net yield of glycolysis is two ATP molecules per molecule of glucose, rendering statement B incorrect.

During glycolysis, the reactants include glucose, ATP, ADP, NAD+, and inorganic phosphate. The products of glycolysis include a net gain of two ATP molecules, two NADH molecules, and two pyruvate molecules. Considering the other statements, glycolysis does produce pyruvate, but it is not directly entered into the citric acid cycle without further modification in eukaryotic cells. The first phase of glycolysis is endergonic, requiring the input of ATP, whereas the latter part of the pathway is exergonic, producing a net gain of ATP.

Final answer:

Genetic engineering in agriculture can involve adding DNA from drought-resistant plants to crop plants, enhancing photosynthesis efficiency, and enabling nitrogen fixation in crops to produce more successful yields in hot, dry climates.

Explanation:

Genetic engineering could be used to produce a more successful crop in a hot, dry climate by adding DNA from plants that are naturally adapted to such conditions into the genomes of crop plants. This process, known as transformation, involves a targeted addition of foreign genes or transgenes into the genome of an organism, which can confer beneficial traits like drought resistance. The new genes could enable the modified crop to withstand extreme climate conditions more effectively, leading to improved crop yields and sustainable agriculture.

One promising application of genetic engineering in agriculture is the modification of photosynthesis efficiency. By using recombinant DNA techniques to double the efficiency of photosynthesis, a significant increase in food and biomass production could be achieved. Moreover, developing the capability for crops like corn, rice, wheat, and cotton to support nitrogen-fixing bacteria would drastically reduce the reliance on synthetic ammonia production, saving energy and natural resources.

Answer and Explanation:

Running or jogging comes under the category of aerobic training/exercise. By definition, aerobic exercise means that the person is training her/his body in the presence of excessive oxygen. So, metabolically speaking, the person is relying on availability of oxygen to carry out metabolism which is mainly about production/supply of energy (ATP) by the breakdown of food in the presence of oxygen. This process is also known as cellular respiration. So, if a person is doing aerobic exercise (running), s/he needs more energy to keep doing the exercise. Typically, aerobic exercise produce more energy (32 molecules of ATP) as compared to anaerobic process (2 molecules of ATP) per reaction run. Thus, In the process of aerobic exercise, the lungs will respire faster to allow more diffusion of oxygen in the blood. Then, this oxygen will be transported to all body by heart pumping and then oxygen enters the cells. Once oxygen is entered, it acts as terminal electron acceptor in a process known as oxidative phosphorylation. This process takes plance in the mitochondria and produces 32 molecules of ATP per reaction.

The organism labelled 2 diverged first.

The correct answer is option b.

Explanation:

The arrows in the diagram indicates the timeline. The branching point shows the event of divergence in a species.

From the diagram the divergence or internal node is shown at point C.

At point C, 2 and 3 are the new species. C is the recent ancestor of the species 2 and 3.

The ancestors of organism 2 diverged first because the timeline is also short in case of species 2.

the C internode or recent ancestor diverged in to 2 different species 2 and 3.

neuron collection of neurons nervouse system and brain

Final answer:

The order from simplest to most complex is the neuron, collection of neurons, nervous system, and then the brain, with the brain being the most complex as it controls numerous vital functions and processes in the body.

Explanation:

If given the terms brain, nervous system, neuron, and a collection of neurons, the order from SIMPLEST TO MOST COMPLEX is as follows:

The neuron is the basic functional unit of the nervous system, each transmitting electrochemical signals. A collection of neurons forms complex networks that can communicate and process information but are less complex than the entire nervous system. The nervous system, comprising the central and peripheral nervous systems, orchestrates the activity of the entire body, making it more complex than just a group of neurons. Finally, the brain, as the command center of the nervous system, is the most complex due to its vast array of functions including consciousness, voluntary and involuntary movement control, and bodily functions.

Roots

Explanation:

Roots gather moisture from the ground for the plant

In plants, roots absorb water and minerals, while leaves perform photosynthesis to produce energy, functioning collectively as the plant equivalent to an animal's mouth.

Plant Structures and Energy Absorption

The structure in plants that most similarly serves the function of a mouth in animals would be roots combined with leaves. While animals ingest food and water through their mouths, plants absorb water and minerals through their roots and capture energy from sunlight using their leaves through the process of photosynthesis. Roots may not directly imbibe 'food' as animals do, but they absorb the necessary water and dissolved minerals from the soil. Leaves then utilize these substances along with sunlight to create energy-rich sugars that fuel the plant’s growth and functions.

Moreover, animals rely on the digestion of consumed organic matter for their energy, whereas plants can manufacture their own food by converting sunlight into chemical energy. This significant difference is key to understanding energy acquisition in the plant kingdom. The structures responsible for this, particularly the leaves, contain chloroplasts with chlorophyll that capture solar energy and convert it into sugars in a process known as photosynthesis. Therefore, roots and leaves together represent the plant equivalent of animal mouths when considering their roles in energy and nutrient uptake.

The genotype of the offspring is likely heterozygous (Bb), with one black feather allele (B) and one white feather allele (W).

In genetics, the color of chicken feathers is often determined by multiple alleles at a single gene locus.

Let's use the letter "B" to represent the allele for black feathers and "W" for white feathers.

Since the chicken with black feathers is denoted as BB and the one with white feathers as WW, we can infer that black feathers (B) are dominant over white feathers (W).

When these two chickens are crossed, the resulting offspring will inherit one allele from each parent.

The genotype of the offspring will be BW, indicating that they carry both a black allele (B) from one parent and a white allele (W) from the other parent.

Despite having both alleles, the phenotype, or the observed trait, is black feathers, as the black allele is dominant.

In a more detailed explanation, the genotype of the offspring can be heterozygous (Bb), with one black allele and one white allele.

However, since black is the dominant trait, the presence of the black allele will determine the phenotype.

This type of genetic cross, involving a dominant and a recessive allele, results in a phenotypic expression that reflects the dominant allele's characteristics.

Facilitated diffusion is a form of passive transport that involves the movement of molecules down their concentration gradient with the help of specific transport proteins.

Facilitated diffusion is a form of passive transport that allows large, polar, or charged molecules to cross the cell membrane with the help of specific transport proteins. Unlike simple diffusion, facilitated diffusion does not require energy and involves the movement of molecules down their concentration gradient. It is important to note that facilitated diffusion only refers to the movement of substances through membrane proteins and not the direct crossing of the phospholipid bilayer.

Answer:

0

Explanation:

This question involves two genes in Betta fish; one coding for body color and the other coding for tail colour. The allele for colored body (B) is dominant over the allele for white body (b) in the first gene while allele for blue tail (T) is dominant over allele for black tail (t) in the second gene.

Thus, in a cross between a Betafish that is homozygous dominant for both genes (BBTT) and homozygous recessive for both genes (bbtt), each parent will produce only one type of gamete combination

BBTT- BT

bbtt- bt

Using this in a punnet square, all offsprings will possess a genotype: BbTt.

Since alleles B and T are dominant, a Bettafish with genotype BbTt will be phenotypically color-bodied and blue-tailed.

Hence, according to the question, the probability of producing an offspring with white body and blue tails will be O since no offspring has such genotype.

The chance of producing an offspring that is white with a blue tail from the described cross in Betta fish is 3/16 or about 18.75%.

To determine the chances of producing an offspring that is white with a blue tail when a Betta fish that is homozygous for having a colored body and a blue tail (BBTT) is crossed with a Betta that is white with a black tail (bbtt), a Punnett square can be used for each trait separately. Since one parent is homozygous dominant for both traits and the other is homozygous recessive, all offspring (F1 generation) will be heterozygous (BbTt) for both traits, displaying the dominant phenotypes: colored body and blue tail.

If two of the F1 heterozygous Betta fish (BbTt) are crossed, the resulting F2 generation will exhibit a variety of genotypes. The traits segregate independently, following Mendelian genetics patterns, which indicate a 9:3:3:1 phenotypic ratio for the two traits when F1 individuals mate.

Therefore, the chance of an offspring that is white with a blue tail (bbT-) will be calculated by determining the probability of the offspring being homozygous recessive for body color (bb) and having at least one dominant allele for tail color (T). This corresponds to 1/4 being homozygous recessive for body color multiplied by 3/4 having a blue tail (since both Tt and TT result in a blue tail), which equals 1/4 * 3/4 = 3/16, or about 18.75%.

Final answer:

The main reason for more cancer deaths in the U.S. compared to poor regions of Africa or Asia is the older population in the U.S. Higher life expectancy and lifestyle factors like smoking contribute to a higher incidence of cancer. So the correct option is c.

Explanation:

The correct answer to the question of why more cancer deaths occur in the U.S. as a percentage of the population than in poor regions of Africa or Asia is c. The population tends to be older in the U.S. This is because cancer is generally a disease associated with aging. The United States, along with other higher-income countries, has a relatively older population due to better overall healthcare and higher life expectancy. As a result, there are more people in the age group who are at a higher risk of developing cancer. Additionally, cancer patterns are influenced by cultural behaviors such as smoking and dietary practices, which are prevalent in the U.S., leading to a higher incidence of cancer-related deaths.

While pollution, a mixed population, and radiation could contribute to cancer rates, they are not the primary reasons for the higher percentage of cancer deaths in the U.S. When considering environmental factors, it's important to note that although poorer regions might face high levels of environmental pollution and related health risks, the younger demographic and issues like infectious diseases often overshadow the impact of cancer in those areas.
