Which capacity makes living beings to adjust in hard environment

Answers

The biological referred to as Adaptation makes living beings to adjust in exhausting atmosphere.

Adaptation, in biology, is that the method by that species measure suitable their several atmosphere, thanks to Natural Selection’s method ensuing into patrimonial variation over many generations.

What is Adaptation?

According to Evolution, Adaptation method is that the process underneath that organisms suits the present atmosphere in conjunction with the modifications thanks to change in atmosphere.

Adaptation is connected with the idea of evolution that was propounded by Darwin and Wallace.

According to Wallace, the evolution of organisms was supported 2 factors: Adaptation and dynamic atmosphere.

To develop the idea of evolution by survival, Wallace and Darwin targeted not solely on straightforward adaptation however additionally proceeded more to clarify however organisms adapt and evolve.

Biologically Adaptation will be in 3 forms:

- Psychological kind

- generative kind

- sequence Frequency

Psychological form- associate degree animal or plant adapt by adjusting consistent with its immediate atmosphere.

Example- modification in temperature or metabolism with a rise in altitude

Reproductive form- method of adaptation thanks to genetic variations among people that is customized i.e. having larger success in—a specific environmental context.

Gene frequency- the method of adaptation happens through associate degree ultimate modification within the sequence frequency relative to blessings bestowed by a selected characteristic, like the coloration of wings within the moths.

Organisms will adapt to associate degree atmosphere in several ways in which. they will adapt biologically, which means they alter body functions

Example- individuals living at high altitudes have evolved changes in their body chemistry and may survive at high altitudes for a brief time as a result of their bodies raise their levels of hemoprotein.

They can additionally exhibit activity adaptation.

Example of activity adaptation is however emperor penguins in Antarctica foregather to share their heat within the middle of winter.

What is theory of Natural Selection?

The theory of survival was given by Darwin in 1859.

Natural selection is that the method through that populations of living organisms adapt and alter.

Individuals in an exceedingly population square measure naturally variable, which means that they're all completely different in some ways in which.

This variation means some people have traits higher suited to the atmosphere than others. people with adaptive traits—traits that provide them some advantage—are a lot of seemingly to survive and reproduce.

These people then pass the adaptive traits on to their offspring. Over time, these advantageous traits become a lot of common within the population.

Through this method of survival, favorable traits square measure transmitted through generations.

Natural selection will cause phylogeny, wherever one species offers rise to a replacement and clearly completely different species. it's one among the processes that drives evolution and helps to clarify the range of life on Earth.

22. An astronaut on the space station tests whether gravity affects the productivity of tomato plants. What
is the independent variable in this experiment?

Answers

When conducting an experiment, the independent variable is always the one that produces or causes an effect or reaction on the dependent variable. In the exposed situation, the independent variable is gravity.

--------------------------------------

During an experiment, you need to consider all the variables involved.

Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified to analyze how another variable responds to it. The researcher changes the independent variable to observe its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, gravity is the independent variable, and influences the productivity of tomato plants. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. Controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.

Along the inferior surface of the liver are several structures that collectively resemble the letter H. The gallbladder and the round ligament of the liver form the vertical superior parts of the H; the inferior vena cava and the ligamentum venosum form the vertical inferior parts.

The gallbladder is a pear-shaped organ localized on the right side of the body, directly under the liver. This organ functions to store a digestive fluid called bile until it's needed for digestion.

The round ligament of the liver (also called ligamentum teres hepatis) is a remnant of the fetal umbilical vein. This ligament is part of the coronary ligament of the liver.

The ligamentum venosum (also called the hepatogastric ligament) is a deep cleft on the posterior surface of the liver. It is a fetal remnant ligament attached to the left branch of the portal vein within the porta hepatis.

oil-rich countries in the middle east cover about 4% of earth's total land area but posses about 48% of the world's known oil reserves. what is the main reason for high concentration of reserves in this part of the world?

Answers

The correct answer is A. Geological processes.

Explanation

Oil is a hydrocarbon of fossil origin by geological processes that transforms large amounts of organic matter deposited on anoxic bottoms of seas or lake areas of the geological past, which were later covered by heavy layers of sediment. This causes organic materials to be transformed into oil by the heat and pressure of the upper layers. However, this phenomenon does not occur in all parts of the earth because in some, as in the case of the Middle East, there were large amounts of organic matter that became an oil reserve. So the correct answer is A.

e) Is this is a silent mutation or a missense mutation? Explain. (1 point)

Answer:

a) mRNA before mutation ⇒ CAG

b) mRNA after mutation ⇒ CAC

c) amino acid before mutation ⇒ Glu, Glutamine

d) amino acid after mutation ⇒ His, Histidine

e) missense mutation

Explanation:

Theoretical frame

Transcription:

Transcription occurs in the nucleus where the template DNI strand is read in direction 3´→ 5´ to build the mRNA molecule in direction 5´→ 3´.

When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: coding strand and template strand.

The coding strand goes in direction 5´ to 3´, while the complementary strand -template strand- grows in direction 3´ to 5´.

The template strand is the mRNA complement.

The coding strand is the same as the mRNA that results from the transcription of the same DNI segment -switching bases T for U-.

The coding strand receives that name because it is the sequence that codes for each amino acid composing the proteins.

Translation:

Translation occurs in the cytoplasm. rRNA and tRNA read mRNA in the direction 5´→ 3´ to build the protein.

Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. There are 64 codons in total, from which 61 codify for amino acids. Because there are 20 amino acids, many codons code for the same amino acid. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.

The codons indicating the initiation or stop points during the translation process are:

• The start codon AUG is the most common sequence used by eukaryotic cells

• The end codons are UAA, UAG, UGA.

When a change occurs in a single base pair, it is known as a point mutation. Points mutations might be either silent, missense, or nonsense. In silent mutations, the resulting mRNA codon codes for the same amino acid as the unmutated sequence. However, if the mutation causes the mRNA codon to code for a different amino acid, this mutation is a missense mutation. Finally, if the mutation causes mRNA codon to be a stop codon, we are referring to a nonsense mutation.

----------------------------------------------------------------------------------------------------------

In the exposed example,

Before mutation

Original DNI base sequence ⇒ GTC ⇒ Guanine, Timine, CytokineTranscripted mRNA sequence ⇒ CAG ⇒ Cytokine, Adenine, GuanineAmino acid ⇒ Gln ⇒ Glutamine

After mutation

Mutated DNI base sequence ⇒ GTG ⇒ Guanine, Timine, GuanineTranscripted mRNA sequence ⇒ CAC ⇒ Cytokine, Adenine, CytokineAmino acid ⇒ His ⇒ Histidine

This is a point mutation, in which the change occurs in a single base pair. The mutation made the mRNA codon code for a different amino acid, meaning that this is a missense mutation.

Before mutation, the mRNA codon is CAG and codes for Glutamine.After mutation, the mRNA codon is CAC and codes for Histidine.

Answers

Answer:

In sexual reproduction gametes fuse to lead to new genetic combinations

Explanation:

In sexually reproducing organisms, there are two parents who create genetically diverse offspring.

This occurs because the gametes of the two parents combine to create very unique genetic combinations, which lead to increased genetic variation.

On the other hand, asexually reproducing organisms reproduce without a partner.

Their offspring are identical clones to the parent, so they have much less genetic variation.

So, the correct answer is that In sexual reproduction gametes fuse to lead to new genetic combinations.

Aquaporins result in a combination of positive charges intracellularly and negative charges extracellularly

What are Aquaporins?

Aquaporin is a group of membrane proteins found in cell membranes and selectively permit water to pass into and out of the cell. Also known as water channels, aquaporins are integral membrane pore proteins. Aquaporins are found in plants, bacteria and animals. They are observed in the vacuolar membranes and plasma membranes. The basic function of most aquaporin is to transport water across cell membranes in response to osmotic gradients created by active solute transport. Aquaporins enable passive transport which means they allow the movement of molecules across a cell without using energy.

What are stem cells?

Stem cells are the primary raw material of the body, the cells that give rise to every other cells with specialized functions.

Under the right circumstances, stem cells differentiate to form the most cells known as daughter cells in the body or in a research lab.

Stem cells are mostly found in bone marrow. This is how they divide in order to produce new blood cells.

Once mature, blood cells end up leaving the bone marrow and reach the bloodstream. A small number of immature stem cells enter the bloodstream.

Bone Marrow has long been thought to be the best source of stem cells.

Previously, if a patient required a stem cell transplant but didn't have access to umbilical cord blood stem cells, they earned a bone marrow transplant.

Thus, this is the reason to have stem cell research as a controversial subject.
