Answer 1

Answer:

An important source of genetic variation comes from mutations. A mutation is a change in the DNA sequence of a gene. Though some mutations are harmful, most are not. A mutation may change a trait in a way that may even be helpful, such as enabling an organism to better adapt to its environment.

The simplest mutation is a point mutation. This occurs when one nucleotide base is substituted for another in a DNA sequence. The change can cause the wrong amino acid to be produced. In some cases, the change has little effect. In other cases, the incorrect amino acid can affect the structure or function of the protein being encoded.

Here’s an example of how this works. This sentence composed of three-letter words is similar to a DNA sequence made up of three-base sequences called codon Now, what happens if one letter is changed?

The sentence now has a different meaning! Notice that the change affects just one word. If this was a DNA sequence, a change in one codon might not cause problems. But in some cases, it can have a severe effect. For example, here’s part of the DNA sequence for hemoglobin, a blood protein that carries oxygen to the tissues

Wolves are predators of deer. What is most likely to happen to the deer population if the wolf population increased?
stay the same
increase
decrease
become extinct

Answers

Hello !⛧bayerife15⛧ I'm glad you asked!

My name is ⚝Tobie⚝ and I will walk you through every step of the way and I will make sure you understand this a bit better!

So what would happen to the deer population if the wolf population increased?

i stay the same

ii increase

iii decrease

iiii become extinct

__________________________________________________________

The population of deer would decrease .

The population of deer would decrease because  the population of wolves

goes up. Since the population goes up they need food and the food they eat

are deer .It would be a bit different if the wolf population decreased .If the

wolf population decreased the deer population would increase which could

lead to overpopulation.

Why are deer important?

Deer are important for our environment because they help other animals

survive and with out them many animals such as wolves and many other

predators would have a hard time catching food.There would be a huge

imbalance in the food chain as well. But when deer overpopulate it becomes

a problem.There will be less food for birds and many other animals.

There would also be a spread in diseases that deer bring .

Hope this helps!

It is most likely that the deer population will decrease as the wolf population increases. Therefore, the correct option is C.

What is Population?

A population is a collection of members of the same species that coexist in the same location and interact with each other. Size, density, age structure, and genetic makeup all contribute to the definition of a population. It is most likely that the deer population will decrease as the wolf population increases.

This is due to the fact that wolves are predators of deer and their hunting will be more frequent as their population decreases. Wolves would have fewer prey to eat as deer populations would decline, which could prevent the expansion of their own populations. A predator-prey cycle describes this interaction between populations of predators and prey, which can lead to changes in population size over time.

Therefore, the correct option is C.

PLEASE HELP!!!! You discover a new protist species. It has chloro-
plasts and vacuoles and moves using a flagellum.
How would you classify the way that it gets energy?
Is it an autotroph, heterotroph, or both? Explain
your answer.

Answers

Answer:

Autotroph

Explanation:

An autotrophic organism is any organism that is capable of synthesizing its own food either by using sunlight (photosynthesis) as an energy source or chemicals (chemosynthesis). An organism capable of photosynthesis must possess CHLOROPLAST (CHLOROPHYLL), which is responsible for capturing sunlight in the cell and also harbors the photosynthetic process.

According to this question, a newly discovered protist is said to have chloroplasts and vacuoles and moves using a flagellum. Due to the fact that this protist possess CHLOROPLAST organelle, it means it can perform photosynthesis, which is one of the ways an autotrophic organism synthesizes it's food. Hence, the organism is AUTOTROPHIC.

In Death Valley, California, there are several ponds that are formed in various areas of the desert. Each pond contains its own species of fish unique to the pond it lives in.

Answers

Answer:

Geographical isolation.

Explanation:

Due to Geographical isolation, there are unique species present in each pond  because they can't inter-breed with one another due to no way of movement to one another location. These unique fish species are geographical isolated from one another which is also responsible for its uniqueness. If they are not Geographical isolated so these fishes mate with each other and their uniqueness will disappear so we can conclude that geographical isolation is responsible for the uniqueness of fish species in each pond.

Answers

Answer:

C) The types of plants and animals that live in the forest are reasonably stable.

The statement that describes a forest ecosystem that has not experienced any natural disasters in the past 100 years is, "The types of plants and animals that live in the forest are reasonably stable," hence option C is correct.

What is a forest ecosystem?

Along with nonliving (abiotic) elements like soil, water, air, and landforms, forests also contain living (biotic) elements like trees, animals, plants, and other life things. A forest ecosystem is made up of all of these elements.

The numerous plant and animal species residing in a forest ecosystem are generally stable if it has not recently been subjected to any disturbances or natural disasters.

Therefore, plants and animals that live in the forest are reasonably stable, so this ecosystem not experienced any natural disasters.

Explanation:

Which Mechanism of microevolution caused the the beak of the medium gound finch population on dafne major to increase in size in size from 1976 to 1978?

Answers

Answer:

Natural selection

Explanation:

Microevolution refers to changes produced at a lower level than species. In genetics, microevolution is the change in the allelic frequency perceptible in a few generations. Most of these naturally produced changes by mutation, natural selection, genetic flux, genetic drift.

After the drought on Daphne Major, many of the plants producing small-sized seeds decreased their reproductive rate drastically. Consequently, there were almost no seeds available for the medium ground finch to feed. The population of this species also decreased to only a hundred birds over two years. Weather conditions and food availability influenced the survival of the animals.

With time, the finched population increased again, but now, the average size of the beaks was larger. The trait modification was related to the availability of only larger seeds with thick husks.

Eating large seeds with medium or small-sized beaks was impossible, so Finches needed to adapt, developing larger beaks to crack open the husks and eat the contents of the seeds.

Natural selection was responsible for the rapid change in the finches´ population beaks size after the drought. The evolutive force modifies the allelic frequencies, increasing the frequency of genetic variants that expressed the larger beak size and declining the frequency of the alleles that expressed smaller beak size.
