help!! Plsss ASAP really neee it

Answer:

They inhabit numerous niches within the forest.

Explanation:

All the biophysical environments where a species lives and how it acquires what it wants for its life and reproduction. In same forest, three separate warbler species live. No, since they occupy the environment, and get nutritional resources across multiple locations on the plant.

Answer:

occupy different niches within the tree

Explanation:

As far as I can tell, the answer would be D. Adaptation. The birds are evolving to adapt to their environment, and as such, their beaks are getting larger to crack larger seeds.

Answer:

Your nose is part of your sinus system (ew!) and it can tell you if you're sick by a runny nose, congestion, and sniffles.

Answer:

It can detect dangers, both inside and outside the body.

Explanation:

Outside of the body, of course, it can smell smoke and things like that, but if you're going into diabetic ketoacidosis, you'll smell a very sweet, fruity smell before you start to have seizures and other effects.

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.

B.  

an asteroid impact likely caused a mass extinction at the end of the Cretaceous.

Explanation:

I did this assinment.

Answer:

B

Explanation:

Answer: These DNA though is long, it is small. it would be half-squished in the nucleus. Because it is half squished, that is why they can be infected by viruses.

This answer not be correct, by the book i read said so.

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:

true

Explanation:

remember- Haploid it sounds like half, so when you think of half, always think of sex chromosomes.  23 chrom.

   diploid- well its the other one so yeah  46 chrom.

Answer:

heat, gas(condensation), Adhesion

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:

They are large molecules that blind readily with proteins , cellulose, starches and minerals.

Explanation:

it hides into leather

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:

B is true

i took the test

Oil is a renewable energy resource. It is processed to make jet fuel. Thus, the correct option is B.

Renewable energy is the energy which is derived from natural sources which are replenished at a higher rate than they are being consumed. Sunlight and wind are the two such sources of energy which are constantly being replenished from the planet. Renewable energy sources are present in plentiful amounts and are found all around us.

Jet fuels are the energy fuels which are typically made by the blending and refining of various crude oils such as petroleum distillation products including naphtha, gasoline, or kerosene in order to meet the specific military or commercial specifications required.

Therefore, the correct option is B.

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.

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

The double recombinants are less frequent ---> Abc and aBC
