<3 also the answer is variation im pretty sure

Any difference between individuals of the same species is called Variation.

Any difference between individuals of the same species is called variation. Variation can manifest in various ways, including differences in physical traits, genetic makeup, behavior, and physiological characteristics. It is a fundamental aspect of biological diversity and plays a crucial role in evolutionary processes.

Variation arises through various mechanisms, including genetic mutations, genetic recombination during sexual reproduction, and environmental influences. Genetic mutations can introduce new genetic variations into a population, while genetic recombination through sexual reproduction can shuffle existing genetic variations. Environmental factors, such as diet, climate, and exposure to different conditions, can also contribute to phenotypic variation.

Variation is essential for populations to adapt and evolve in response to changing environments. It provides the raw material for natural selection, a process by which certain variations are favored or selected for in a population, leading to evolutionary changes over time. Variation allows individuals to possess different traits and characteristics, some of which may confer advantages in specific environmental conditions, while others may be disadvantageous.

Understanding and studying variation is crucial in fields such as genetics, evolutionary biology, and ecology. It helps scientists understand the mechanisms driving genetic diversity, the processes of speciation and adaptation, and the dynamics of populations and ecosystems. Variation also has practical applications in fields such as agriculture, medicine, and conservation, where knowledge of genetic and phenotypic variation can inform breeding programs, medical treatments, and conservation strategies.

Answer:

The stop codon mutation in Lucy's ADA gene stopped her ADA protein from working by putting a hault to the process of translation.

Explanation:

This stopped it from working because it lead to a protein that was then nonfunctional.

Answer:

Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis. They also help to reduce water loss by closing when conditions are hot or dry. Stomata look like tiny mouths which open and close as they assist in transpiration.

Answer:

The double recombinant individuals are less frequent ---> Abc and aBC

Explanation:

We can know if genes are linked, by looking at the progeny distribution. In a tri-hybrid cross, If individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1:1:1:1:1. If we observe a different distribution, meaning that phenotypes appear in different proportions, we can assume that genes are linked in the heterozygote parent.

We can recognize the parental gametes because their phenotypes are the most frequent in the descendants, while the double recombinants are the less frequent. Finally, the simple recombinant gametes are the ones with intermediate phenotypes frequencies.  

In the present example, the phenotypic ratio shows different proportions than the expected ones if they were not linked.

We can recognize the parental gametes in the descendants because their phenotypes are the most frequent,

while the double recombinants are less frequent.

And simple recombinant gametes produced by the cross, which frequencies are intermediate.  

a. Which phenotype represents the double crossovers

Answer:

rotation

Explanation:

circle is 360 degrees

Moving your limb through a full 360 degree circle is called rotation of your limb.

Rotation is the process of moving an object or a body from a central position, through the circumference of that position.

This type of motion is usually 360 degrees movement because it involves a complete circle or turn.

Thus, moving your limb through a full 360 degree circle is called rotation of your limb.

Answer:

a.) The electrons provide energy for the H+ pump to transport more H+ ions into the thylakoid space.

d.) The photolysis of water releases H+ ions into the thylakoid space.

Explanation:

The thylakoid, which is found in the chloroplast, is the site of the first stage of photosynthesis (LIGHT DEPENDENT STAGE) in the cells of plants. The light stage of photosynthesis functions to produce energy (ATP) and NADPH for the second stage called Calvin cycle.

However, this ATP is generated by the power realized from the pumping of Hydrogen ions (H+) into the thylakoid lumen. The following causes the build up of H+ ions in the thylakoid space:

- Light photon hits the chlorophyll molecule, which is the photosynthetic pigment, to become charged. The electrons (e-) generated from this provide energy for the H+ pump to transport more H+ ions into the thylakoid space.

- Photolysis of water, which involves the splitting of water to produce hydrogen ions (H+) causes a build up of H+ in the thylakoid space.

Answer: warm front

Explanation: When a warm air mass meets a cold air mass, the warm air rises since it is lighter. At high altitude it cools, and the water vapor it contains condenses. This type of front is called a warm front. It generates nimbostratus clouds, which can result in moderate rain.

Answer:

Using the food chain which originates from the sun's energy.

Explanation:

Answer:

matter moves through an ecosystem through the recycling of energy and nutrients between different trophic levels. The first trophic level consists of primary producers like plants that can be manufactured their own food through photosynthesis. Similarly plants are require nutrients like nitrogen to grow.

Explanation:

Image result for How does energy and matter move through the ecosystem

In ecosystems, matter and energy are transferred from one form to another. ... Decomposers break down dead plant and animal matter. Producers (plants) use sunlight and other nutrients to make their own food through photosynthesis. Consumers are the animals that consume, or eat, other living things.
