Answer:
B
Explanation:
Photosynthesis requires sunlight and produces glucose but animals do not carry out photosynthesis and animal cells do not have the chloroplasts to absorb sunlight. Therefore A is false as is C and D as respiration uses glucose and does not produce it. And respiration transfers energy to cells that needs it therefore sunlight energy is not required.
Hope this helps.
Photosynthesis and cellular respiration are interrelated processes where photosynthesis creates glucose and oxygen, which are then used in cellular respiration to produce energy, carbon dioxide, and water. They function as opposite halves of a cycle that facilitates the energy flow within ecosystems and helps regulate the levels of carbon dioxide and oxygen in the atmosphere.
Explanation:Photosynthesis and cellular respiration are related in that they are essentially opposite processes that work together to facilitate the flow of energy through living organisms. Photosynthesis is a process used by plants, algae, and certain bacteria to convert light energy from the sun into chemical energy stored in glucose, releasing oxygen as a byproduct. Cellular respiration is a process that all living organisms perform, in which oxygen and glucose, produced by photosynthesis, are used to generate ATP, the energy currency of the cell, with carbon dioxide and water being released as byproducts.
To sum up, while photosynthesis converts carbon dioxide and water into glucose and oxygen using the sun's energy, cellular respiration converts glucose and oxygen back into carbon dioxide and water while releasing usable energy stored in ATP. This cyclical relationship is critical for the energy flow and the constant recycling of carbon dioxide and oxygen in the Earth's atmosphere. It forms part of the larger carbon and energy cycle of our planet.
How do bacteria cause disease?
A. A bacterium injects its DNA into the genome of a host cell.
B. A bacterium reproduces inside a host cell and causes the cell to
break open.
C. A bacterium replaces the host cells with bacterial cells.
D. A bacterium releases harmful proteins or other poisons into the
host's body
Answer:
A Bacterium injects its DNA into the genome of the host cel. (Ans. A)
Explanation:
This stage of bacteria causing disease is known as Lytic cycle ,in this cycle phage 1st binds to the receptor present on the surface of the bacterial cell. Then the phage injects its DNA into the host cell and then protein synthesis and DNA coping occurs. The capsid proteins are stuffed with DNA to make lots of new phages particles.
how many base pairs would a DNA segment of length 1.36mm have?
Answer:
4.0 million
Explanation:
The average length of a base pair (bp) is 340 pm (340 × 10^-12 m)
Length of DNA = Number of bp × length of each bp
1.36 × 10^-3 m = bp × 340 × 10^-12 m
bp = (1.36 × 10^ -3)/(340 × 10^-12) = 4.0 × 10^6
The DNA segment would contain 4.0 million bp.

Disturbances inside Earth’s core cause earthquakes. The starting point of the disturbance is called the epicenter. Why does the amplitude of a seismic wave usually decrease as the wave moves away from the epicenter?
Answer:
The energy released by the earthquake spreads throughout a larger volume of Earth.
Explanation:
At farther distances the amplitude of the seismic waves decreases as the energy released by the earthquake spreads throughout a larger volume of Earth. Also with increasing distance from the earthquake, the waves are separated apart in time and dispersed because P, S, and surface waves travel at different speeds.

The value of x is 3.
Since f(3)=64 it means the population of bacteria is 64 in 3rd hour.
Therefore the correct option is A.
Which best describes how an organism’s niche is determined
Answer:
The answer is....
Explanation:
An organism's habitat and ability to reproduce determine its niche.
An organism's niche is determined by several factors, primarily its competition for resources, the features of its physical and geographic environment, and its unique nutritional and reproductive strategies.
Explanation:An organism's niche in an ecosystem is determined by several factors tied to both its unique characteristics and the properties of the environment. These factors range from the resources it consumes, to its interactions with other species, to the physical features of its habitat.
Firstly, competition for resources such as food, water, sunlight, and mineral nutrients plays a significant role in determining an organism's niche, due to the restrictions imposed by the principle of Competitive Exclusion. This principle asserts that two species cannot occupy the same niche in a habitat, implying that they can't compete for all the same resources and still coexist in the same community.
Moreover, the components of an organism's physical and geographic environment, such as the habitat's climate, topography, and available species, are also essential determinants of its niche. This is because they significantly impact which organisms can exist within a specific area.
Lastly, an organism's nutritional and reproductive strategies add to the determination of its niche. These strategies depend upon the type of organism, its nutritional requirements, and the type of habitat it inhabits.

Cells divide in two stages: Meiosis - haploid cell division [½ number of chromosomes], and Mitosis - diploid cell division [same number of chromosomes]. Their objective is to produce offspring, which means reproduce.
I am joyous to help. Anytime.
Cells divide for multiple reasons, including reproduction, preventing tumor formation, and increasing their surface area-to-volume ratio.
Explanation:The reason cells divide is:
To reproduce: Cell division allows for the production of new cells, enabling growth and development in multicellular organisms, as well as reproduction in single-celled organisms.To prevent tumor formation: Cell division is tightly regulated to ensure that cells do not divide uncontrollably and form tumors. When cells divide, they undergo a process called mitosis, which helps maintain proper cell growth and avoid tumor formation.To have a smaller surface area: In certain cases, cells divide to increase their surface area-to-volume ratio.

Density dependent factors refers to those factors that their impacts depend on the size of the population. Example of such factors are food availability, predation, migration and diseases.
Density independent factors on the other hand refers to those factors that affect population size regardless of their sizes. Examples of such factors are temperature, natural disasters, human activities, etc.
In the question given here, the clear cutting of the rain forest is brought about by human activity and is an example of density independent factor.
The answer is A. Clear cutting the rain forest because it is a human activity and that does not depend on the population size of a place.
Which of the following best helps scientists determine the order in which a species evolved? (2 points)
Type of fossil
Geographic location of the fossil
Location of the fossil in Earth's layers
Species of the fossil
The location of the fossil in Earth's layers helps scientists determine the order in which a species evolved.
Explanation:The correct answer is Location of the fossil in Earth's layers. The study of fossils and their position in the rock layers, known as stratigraphy, can help scientists determine the relative age of different fossils and the order in which species evolved. By examining the layers of rock, scientists can identify the sequence of fossil species, with older fossils found in lower layers and more recent fossils found in higher layers.
The option that best helps scientists determine the order in which a species evolved is the location of the fossil in Earth's layers. This method is central to the field of stratigraphy, which studies the layers of sedimentary rock to establish a timeline for events. The principle of superposition is key in this field; it states that in undisturbed layers of rock, the oldest layers are at the bottom, and each subsequent layer is younger than the one beneath it. So, fossils found in deeper layers are typically older than those found in layers closer to the surface.

Global warming will increase temperatures through the northern United
States. What will most likely be the effect on wildlife in this region?
A. They will have more access to fresh water.
B. They will have more access to food.
C. They will die unless they are able to move to cooler areas.
D. They will be healthier in the warmer weather.
Answer: C
Explanation: C is the only negative effect of global warming. They must move to a different location or die.
The correct answer is C. They will die unless they are able to move to cooler areas.
Explanation:
The global warming phenomenon implies a long-term change in temperature all around the world. This change in temperature represents an important thread for ecosystems as biological processes and natural cycles are closely linked to temperatures. Indeed the rise in temperatures has caused changes in migrations, pollination, and availability of resources which leads to the extinction of species that cannot adapt to warmer climates. For example, in oceans higher temperatures had caused corals and some fish to die as they are adapted to only certain temperatures. Therefore, the most likely effect on wildlife due to global warming in the U.S. and other regions is that animals, plants and other organisms will die unless they move to cooler areas (Option C).

A skeletal muscle is a composition of several components bundled one into the other. At which structural level in the muscle does contraction occur
to bring about contraction in the whole muscle?
Answer:
The correct answer will be- myofilamants-actin and myosin.
Explanation:
The skeletal muscle is made up of the muscle fibers which are cylindrical cells enclosed by layers. The muscle cell is divided into smaller units, the smallest of which is myofilaments.
The myofilaments are composed of the thin filaments called actin and thick filaments called myosin which together forms the functional unit of a muscle known as the sarcomere. The muscle contraction takes place due to the sliding of these actin and myosin over each other as a result of the signals arrived from the CNS.
Thus, myofilaments-actin and myosin is the correct answer.
which of these practices does the most to decrease the amount of water needed to farm?
A-drip irrigation
B-crop rotation
C-cash crops
D-no-trill farming?
The practice that does the most to decrease the amount of water needed to farm is (A) drip irrigation.
What is Drip irrigation?Drip irrigation is a type of irrigation system that delivers water directly to the roots of plants, drop by drop, through a network of tubes and emitters.
This system uses water much more efficiently than traditional methods of irrigation, such as flood irrigation or sprinkler systems, because it delivers water precisely where it is needed and minimizes evaporation and runoff.
Crop rotation, cash crops, and no-till farming are also practices that can help to conserve water in agriculture, but they do not have as significant an impact on water use as drip irrigation.
Crop rotation involves planting different crops in a specific sequence to help maintain soil health and fertility, while cash crops are crops that are grown primarily for sale rather than for subsistence. No-till farming involves leaving the soil undisturbed between crops to help reduce erosion and conserve soil moisture.
Overall, while each of these practices can contribute to water conservation in agriculture, drip irrigation is the most effective in reducing the amount of water needed to farm.

C. Skin that blends in with green plants
D. Very small leaves to trap water
ANSWER:
The correct option is C: Skin that blends with green plants. Most animals in rain forests are green so that they can camouflage and appear like plants.
EXPLANATION:
Adaptation is the way in which animals survive in different climatic conditions and different regions. In rain forests, to protect themselves and to find food, most animals are green in colour. This prevents the animals from being spotted easily and therefore they are protected from hunters and other animals that eat them. This way, the animals can also find their prey and catch it easily.Answer: c <3

What is a five carbon sugar
Answer:
The 5-carbon sugars ribose and deoxyribose are important components of nucleotides, and are found in RNA and DNA, respectively. The sugars found in nucleic acids are pentose sugars; a pentose sugar has five carbon atoms. A combination of a base and a sugar is called a nucleoside.Explanation:
A five carbon sugar is a monosaccharide that contains five carbon atoms and is found in nucleic acids. Examples include ribose and deoxyribose.
Explanation:A five carbon sugar is a monosaccharide that contains five carbon atoms in its structure. Two examples of five carbon sugars found in nucleic acids are ribose and deoxyribose. Both have a cyclic form with a hydroxyl group at the anomeric position. Five-carbon sugars, or pentoses, are crucial components of nucleic acids like DNA and RNA. Ribose and deoxyribose are common examples.
Their distinctive features include a five-carbon backbone, where each carbon is attached to a hydroxyl group. In RNA, the 2' carbon of ribose contains a hydroxyl group, distinguishing it from deoxyribose in DNA. The arrangement of these carbons and hydroxyl groups contributes to the unique structure and function of these essential building blocks in genetic materials.
