Explanation:

Sorry if i am wrong!

Answer:

[tex]\huge\boxed{\sf Sick\ animals\ to\ live\ longer}[/tex]

Explanation:

Predators usually prey upon sick animals so that the best among the specie is able to reproduce and produce the most fertile offspring. This maintains the cycle of nature. If too many predators are killed, it will cause sick animals to live longer. As a result, they will reproduce and the offspring will not be healthy enough which in future, can cause many problems.

Which of the following is true of active transport?
A In active transport, the cell does not have to do any work as nature moves the materials across the cell membrane.
B The energy used by the cell is in the form of the ADP molecule
C In active transport, the cell must push or pump the molecules from areas of high concentration to areas of low concentration.
D Molecules called pumps function to control active transport.

Answers

Answer:

D. Molecules called pumps function to control active transport.

Explanation:

Active transport is one of the two types of transport (the other being passive transport). It is the type of transport in which substances move against their concentration gradient i.e. from a lower concentration to a higher concentration. Hence, due to this, energy input in form of ATP is required by the cell.

However, the process of active transport makes use of certain molecules called PUMPS to control it. The pumps moves ions/molecules against their concentration gradient. An example is the sodium-pottasium pump which moves sodium ions from a region of low conc. to a region of high conc.

what is brain cancer ?

Answers

Answer:

Brain cancer is an overgrowth of cells in your brain that forms masses called tumors. Cancerous, or malignant, brain tumors tend to grow very quickly. The symptoms of brain cancer depend on the size and location of the tumor.

Common brain cancer symptoms include:

headaches that are usually worse in the morning

nausea

vomiting

a lack of coordination

a lack of balance

difficulty walking

memory lapses

difficulty thinking ,speech problems

.Many of the symptoms of brain cancer are also caused by other, less serious conditions. There’s no need to panic if you’re experiencing these symptoms, but it’s a good idea to visit your doctor to have your symptoms investigated, just in case.

Why do the cells of the digestive system secrete proteolytic enzymes, such as pepsin, in their inactive forms

Answers

Answer:

In the initial stages of digestion of food, the stomach performs an essential role. Apart from doing churning and squeezing the food bolus, it also discharges an amalgamation of compounds, together called gastric juice. It comprises mucus, water, pepsin, HCl, and intrinsic factor. Of these five constituents, the principal enzyme that takes part in the digestion of protein is pepsin.

It dissociates proteins into amino acids and smaller peptides, which can easily get captivated within the small intestine. This pepsin is released in its sedentary form, or zymogen form called pepsinogen by the chief cells present within the gastric lining. It is released in its sedentary form by the stomach, by this the stomach inhibits the auto-digestion of defensive proteins in the digestive tract's lining.

Why is the birth of modern science (c.1500-1700) important to how we understand knowledge and disciplinary divisions today

Answers

The correct answer to this open question is the following.

Although there are no options attached, we can say the following.

The birth of modern science (c.1500-1700) was important to how we understand the knowledge and disciplinary divisions today because the scientific method was established to get proper validation to the things in nature that in the past were attributed only to dive concepts expressed by the Church.

That old fashion way of thinking, validated by the church during the dark ages of Medieval Times, only created fear and fostered ignorance in people.

The advent of modern science changed this thing, basing its theories and answers on proper research that could be proven. That is how the human mind expanded and grew. No more myths and distorted religious beliefs that were so wrong.

Which phrase does not describe asexual reproduction in organisms?

1-little variation in offspring
2-duplicates its genetic material
3-only one type of cell involved
4-requires two parents

Answers

Answer:

4

Explanation:

asexual reproduction means only one parent

It requires two parents, does not describe parthenogenesis in organisms.

The correct option is 4.

What is parthenogenesis?

Parthenogenesis is the process in which reproduction happens without the fertilization of sperm.

It is the development of an embryo without fertilization of the egg.

Animals such as bees, wasps, and ants, do parthenogenesis.

It includes only one parent.

Thus, the correct option is 4, which requires two parents.

How do you create a dichotomous key?PLEASE WRITE IT GOOD BC I HAVE A TEST TOMORROW ​

Answers

Answer:

In the field of biology, classification plays a major role. With new species being discovered every day, it’s important to have techniques in place to identify and classify them. One such tool is the dichotomous key. It helps identify organisms by directing the user to look at the known organisms.

Explanation:

What is a Dichotomous Key

What is a Dichotomous KeyStudents and professionals use the dichotomous key to identify and classify objects (i.e. people, animals, plants, bacteria, etc.) into specific categories based on their characteristics. It’s the most commonly used form of classification or type of identification key used in biology as it simplifies identifying unknown organisms.

How can point and frameshift mutations contribute to biodiversity of Earth? Explain your
answer.

Answers

Answer:

These mutations form new alleles that increase genetic variation in a population. This variation may lead to new species which increases biodiversity.

Explanation:

Mutations are randomly occurring modifications that exist within the genetic code, leading to replication errors in DNA. DNA molecules are long-chain, helical macromolecules that store genetic material. They consist of different monomer sequences called nucleotides. In a reading frame, which contains instructions for protein production, they shape base pairs and codon sequences.

Single nucleotide polymorphisms are normal, as silent mutations, which sometimes result in no changes in amino acids. Some mistakes add a random nucleotide (SNP) in point mutations resulting in new alleles.

Frameshift mutations occur from nucleotide insertions or deletions that are not divisible by 3. This results in the codon requiring more or fewer nucleotides which disrupt the reading frame, resulting in a separate protein translation.

In Camellia flowers, petal color is inherited codominantly with the possible colors
being red, white, and red and white spots. What would be the chance of getting a
red and white spotted flower if you cross a spotted flower with a white flower?

Answers

The chances of getting a red and white spotted flower if you cross a spotted flower with a white flower are - 25%.

Codominance

This is an inheritance pattern in which both the alleles of a gene are expressed in an organism. In the camellia plant, alleles R and allele W will express themselves independently of each other.

Due to this, in heterozygous condition (RW) the phenotype appears as a hybrid that is presence of red and white patched flowers.

Crossing:  a spotted flower (RW) with a white flower (WW)

punnet:

        R       W

W     RW     WW

W    RW     WW

As we know only RW is heterozygous that expresses spotted flower, in this case, only a 25% probability of spotted flower.

What is Codomince?

In terms of genetics, codominance is a sort of inheritance in which two distinct expressions (alleles) of the same gene result in distinct features in a person. That is, both qualities emerge rather than one trait predominating over the other, as in a plant or animal with multiple pigment colors.

One common characteristic of people that you can't really see just by looking at them, but that many people are aware of, is their blood type.

One A allele and one B allele are present in individuals with the blood type AB. Their blood type is AB because both alleles are expressed simultaneously.
