What is number 2 & 3 ?

Answer:

An outbreak of a disease that infects squirrels in the park.

Explanation:

All the other answer choices would increase the population of squirrels. For the first option, more trees = more habitats = more squirrels to live in. For the second option, less hawks = less predators = more squirrels that will survive. For the third option, heavy rain = more acorns = more food for more squirrels.

Only the last option would limit the growth of a population of squirrels since diseases kill organisms in a population.

Answer:

1) Snakes and Hawks

2) Frogs and Snakes

Explanation:

1) The snakes and the hawks both eat frogs.

2) The frogs and snakes both eat grasshoppers.

Answer:

because natural selection only acts on traits that impact reproductive success.

Answer:

Habitat is the natural home or environment of an animal, plant or other organism.

Answer:

ATP

Explanation:

Answer:

The answer is ATP

Explanation:

During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP

I believe it is called "codominance"

Answer:

Phospholipids arrange in two layers. Fatty acid chains from each layer are "sandwiched" in the middle away from water in and out of the cell.

Explanation:

Answer with explanation:

If a body system does not work properly then the other body systems will also fail because every system is needed for a person to live properly. For example if the respiratory system does not work properly then the other systems will be harmed as oxygen will not be able to move to other parts of the body. As a result, the kidneys will fail and the heart will stop working and the person will die.

One body system that is not functioning properly can affect another body system because, in an organism, coordination is maintained by the different organ systems. If one system is affected, then others will be too.

In a multicellular organism, the organism is regulated by the coordination of the different organ systems, such as the circulatory system, digestive system, etc. In the human body, many systems are present, and each system is made up of many organs. In the nervous system, the nerves, brain, and spinal cord are involved, in the circulatory system, the blood, blood vessels, heart, and lungs are involved, and the lungs are involved in the respiratory system too. Because a single organ is involved in multiple organ systems, if one system is affected, the others will be affected as well.

Hence, one body system that is not functioning properly can affect another body system because, in an organism, coordination is maintained by the different organ systems.

Answer:

D. Climate change

Explanation:

The carbon cycle is disrupted by several activities of man which includes burning if fossil fuels anong others. These leads to accumulation of huge amounts of carbon dioxide in the atmosphere which leads to global warming. The resultant effects of global warming is what one of the major cause of climate change.

Therefore, human disruption of the carbon cycle can be said to have been implicated in climate change.

Answer:

how are they making you do that in an hour

Explanation:

Answer:

When all of the populations live together in the same area, it is called:

A community

Why? Because a community occurs when multiple people are together, and the prefix com means "together".

When all type of the populaton lived together in the similar area so we called them as the community.

The population means the group of individual that are interbreeded with respect to the same species that should be isolated from the other group

while on the other hand, the community means the group or two or more various species that have the similar kind of geographical area.

Therefore, the option A is correct.

Answer:

by using molecular clocks which are based on the mutation rates among molecular sequences (e.g., DNA sequences). The mutation ​rate can be used to estimate the times of divergence between sequences (in this case, between duplicated sequences in the target species and non-duplicated sequences in the most recent common ancestor).

Explanation:

A molecular clock is a technique that uses the mutation rate (μ) to measure the association between evolutionary rate and time. A mutation rate can be used to estimate the time in prehistory when two or more molecular sequences diverged. For example, assuming a generation time of 20 years, a species that has 100 mutations per generation is divided by 20 years to yield a mutation rate equal to 5 mutations per year. In consequence, the times of divergence can be estimated by dividing half of the target genomic region length (in nucleotides) by the mutation rate (t = d/2 ÷ μ).

Answer:

a. Reduces represor binding.

b. Constitutive expression of the operon.

c. Stronger promoter if it is more similar to the consensus sequence. Weaker promoter if less similar.

Explanation:

The lac operon is an operon required for lactose transport and metabolism in enteric bacteria such as Escherichia coli. It is regulated by glucose and lactose availability and consists of the following structural genes:

The lac operon is under a type of negative regulation, where genes can always be transcribed, except when the Lac I repressor protein is bound to the operon region, for which it has a high affinity. In this case, the promoter of the lac I gene is constitutive, so the Lac I protein is permanently expressed and remains bound in tetramer form to the operon region, preventing the transcription of structural genes.

Since lactose is the inducer of the operon, it is able to bind to the Lac I repressor protein and generate a conformational change that decreases its affinity for the operon region. Thus, the operon region is left free, RNA polymerase can freely transcribe the structural genes and β-galactosidase can degrade lactose to glucose plus galactose. In the absence of lactose, the Lac I repressor protein maintains its high affinity for the operator region, preventing RNA polymerase from transcribing the structural genes. In this way, the system remains closed with consequent energy savings for the bacterium.

As a final clarification, actually the true inducing molecule of the lac operon is called allolactose, an isomer of lactose obtained by a transglycosylation occasionally carried out by β-galactosidase.

a. When there is a mutation in the lac operator that deletes most of the operator, then the repressor Lac I can no longer bind and RNA polymerase will begin transcription.

b. When there is a mutation in the Lac I gene that eliminates the binding of repressor to operator, then this protein can not produce the repression so there would be a constitutive expression of the operon.

c. Since the promoter us a region of DNA recognized by RNA polymerase for transcription, if there is a mutation here it will generate a stronger promoter in the case that this part is similar to a consensus sequence (the most commonly encountered nucleotides found at a certain location). In the case that it is less similar, then it will generate a weaker promoter.
