The ability of an organism to change internally or externally in relation to changes in the environment is called _____. reproduction complexity heredity homeostasis

Answers

D. Homeostasis 

Homeostasis is the constant process of regulating the functions of a body.

Answer:

The correct answer is homeostasis.

Explanation:

Change in an organism internally or externally according to environmental change is called homeostasis. This ability help organism to maintain and regulate equilibrium to the outer environment to keep their vital function. There are many regulating organs or glands that help in maintaining homeostasis.

Hypothalamus located in the brain is the major organ that helps in regulating homeostasis. The homeostasis action involves common things are body temperature, blood pressure regulation and many more. however, in lower life forms, it can be regulated by localized organs or cells too.

Thus, the correct answer is homeostasis.

A polygenic trait can have

A. Fewer genotype than most single-gene traits.

B. Many possible genotypes, but few possible phenotypes

C. Fewer phenotypes than most single-gene traits.

D. Many possible genotypes, producing many possible phenotypes.

Answers

I believe the correct response would be D. A polygenic trait encodes for something as melanin concentration in one's skin, skin colour, height etc. These vary quite immensely from person to person, for instance, and can not only be stated as discrete categories in terms of phenotype, as short and or tall. Since the many phenotypes are based on the appropriate Genotypes, there must be many possible Genotypes as well to code and or provide for these diverse phenotypes within a given polygenic trait.
Final answer:

A polygenic trait can have many possible genotypes, producing many possible phenotypes.

Explanation:

A polygenic trait can have many possible genotypes, producing many possible phenotypes. Polygenic traits are controlled by multiple genes, with each gene contributing a small effect to the final phenotype. This results in a wide range of phenotypes that can be observed for a polygenic trait, such as height or skin color.

For example, height is a polygenic trait influenced by multiple genes. There are many possible combinations of genes that can determine an individual's height, leading to a continuous distribution of heights in a population.

Therefore, the correct answer is option D. A polygenic trait can have many possible genotypes, producing many possible phenotypes.

What stores information in a cell

Answers

The answer is DNA in the nucleus:

Inside the cells, genetic information is organised inside the nucleus. A biological information is stored on DNA in the nucleus. DNA contains information and instructions for the cell, hence it stores genetic information.
Final answer:

DNA, or deoxyribonucleic acid, is the molecule that stores genetic information in a cell. It carries the instructions for a cell's functions and replication and is found in the nucleus in eukaryotic cells and the nuclear zone of prokaryotic cells. Gene expression and cellular differentiation are dictated by DNA.

Explanation:

The information in a cell is stored in the form of deoxyribonucleic acid, commonly known as DNA. DNA is a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses. DNA stores the information needed to build and control the cell through the sequence of its four bases: adenine, thymine, guanine, and cytosine.

DNA replication is critical for the transmission of genetic information from one generation of cells to the next, ensuring that each new cell receives a complete set of DNA. This occurs in the nucleus of eukaryotic cells, and a specific nuclear zone in prokaryotic cells. The DNA molecule is composed of a long chain of nucleotides, each of which consists of a 5-carbon sugar, a phosphate group, and a nitrogen-containing base.

Furthermore, our understanding of how DNA stores and utilizes genetic information comes from the discovery of its structure by Watson and Crick in 1953. This discovery has been essential for modern biology, helping us understand the process of gene expression and how different cell types are formed, despite having the same genetic code.

Dolly was a female domestic sheep, and the first mammal to be cloned from an adult somatic cell, using the process of __________________.
A) DNA transfer
B) cell transfer
C) oocyte transfer
D) nuclear transfer

Answers

The answer is D)Nuclear transfer

Answer: The correct answer for the blank is-

D) nuclear transfer.

Dolly was a female domestic sheep, and the first mammal that was cloned using an adult somatic cell ( particularly a mammary gland cell from a Finn Dorsett sheep). She was produced using a technique, which is termed as somatic cell nuclear transfer.

In this technique, the nucleus from an adult somatic cell was transferred to an unfertilized oocyte ( which was first enucleated that is nucleus was removed). After this, unfertlized egg was activated using electrical stimuli, which initiated cell division and produced Dolly.

Thus, option D) nuclear transfer is the right answer.

A bacterium is placed in a hypertonic solution. Which of the following would the bacterium use to maintain osmotic pressure?

a. Active transport
b. Ion pumps
c. Facilitated diffusion
d. Contractile vacuole

Answers

the answer to this one is c.

Answer:

c. Facilitated diffusion

Explanation:

The bacteria shown in the question is in a hypertonic solution. Thus, we can conclude that the solution contains a higher solute concentration than the solute concentration inside the bacteria. For the osmotic pressure to be maintained the bacteria will receive solution solutes until the concentrations are balanced. This process is done through facilitated diffusion.

Some substances have certain characteristics that make it impossible for them to cross the cell's lipid bilayer by simple diffusion. However, they can also pass the membrane by passive transport, this type of process known as facilitated diffusion. In this way, particles can enter or leave the cell through their attachment to specific proteins, known as carrier proteins, or through aqueous pores of protein channels, both present in the cell membrane.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer: d. They will undergo evaporation and change to a gas. ...?

Transpiration is a process of loss of excess water from the small pores present on underside of leaves. The water released by this process evaporates and converted into water vapor (gas). The water vapors formed by this process are released in the atmosphere. The rate of transpiration depends upon weather conditions, such as humidity, sunlight, temperature, and wind.

A virus is unlike an organism in that the virus cannot reproduce outside a living cell.
Organisms can reproduce independently, whereas viruses have to "kidnap" other cells and settle there in order to make an "offspring."

A virus is unlike an organism in that the virus is not considered a living organism.

Unlike organisms, viruses lack the essential characteristics of life, such as the ability to grow, reproduce independently, and carry out metabolic processes.

Instead, viruses are obligate intracellular parasites that require a host cell to replicate and carry out their life cycle. They consist of genetic material (DNA or RNA) enclosed in a protein coat but lack cellular structures or machinery.

Viruses cannot perform vital life functions on their own and are inert outside a host cell.

Their replication involves hijacking the host cell's machinery to produce new viral particles, highlighting their distinct nature from living organisms.

Answers

The correct answer is (b) water storage.

Savanna is a tropical place  located in which has high temperature round year.The savanna plants had adapted many adaptation to protect themselves from drought. They adapted a water storage organ called baobab.These are long cylindrical shaped trunk used to store water in dry conditions.This adaptation was necessary to store water for the times when there is a scarcity of water.These adaptation are necessary so that the trees can regrow in the next season after drought.







Final answer:

Savanna plants have adaptations like water storage, spines, and bitter taste to aid them during droughts.

Explanation:

Savanna plants have several adaptations to aid them during droughts. One of these adaptations is water storage. Plants like cacti have modified stems that can store water, allowing them to survive long periods without rain. Another adaptation is spines. These spines reduce the surface area of leaves, minimizing water loss through evaporation. Lastly, some plants develop a bitter taste as an adaptation. This helps deter herbivores, ensuring the plant's survival during dry periods.
