Answer:

desert

Explanation:

the sun plays a big part

Answer:

[tex]\boxed {\boxed {\sf Desert}}[/tex]

Explanation:

Let's evaluate the information given.

Large ears

Obtains water from food

Burrows underground during the day

Based on this information, we can assume this is a desert animal. In the desert it is very hot (adaptations of large ears and undergrounds burrows) and there is little water (gets water from food).

Answer:

We now know that meiosis is the process of chromosomal reduction which allows the production of haploid germ cells necessary for sexual reproduction. Meiosis is furthermore important for its role in enabling genetic diversity and facilitating the repair of genetic defects through recombination.

Explanation:

Brainliest please?

Meiosis is a specialized form of a cell division in which number of chromosomes is reduced to half. The reduction in chromosome number is achieved by one round of DNA replication and two rounds of chromosome segregation.    

The correct answer is option B. The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.

Other options-

A. Meiosis creates diversity by cutting each chromosome exactly in half - incorrect .In meiosis the chromosome number is reduced to half.

C. It creates sex cells (egg or sperm) that have exactly the same alleles (version of a gene) as the parents-incorrect. The sex cells produced are not genetically identical to the parent cell.

D. The chromosome in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy-incorrect. In meiosis the chromosomes are not exactly copied.

Answer:

lipids

Explanation:

Answer:

Oxygen and glucose are both essential for energy production.

Explanation:

Glycolysis is the break down of sugar with or without the presence of oxygen to provide energy to our cells. The energy for the cell is in the form of ATP. In the presence of oxygen the process is much more efficient and is the last step in oxidative phosphorylation. In this process the Oxygen will pick up the protons that have driven the proton motif force that was used to turn the ATPase that was used to make ATP. The oxygen picks up these protons and keeps the cell pH stable and this is called metabolic water. The Dr should check the blood for the presence of both glucose and oxygen.

Answer:

A. 15%

Explanation:

DNA is composed of four nitrogen bases: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). Chargaff's rule of base pairing states that A always pairs with T, while G always pairs with C. The total distributed percentage of the four 4 nitrogen bases must be equal to 100%. In this case, the C content is 35%, thereby G=35% (i.e., equal to C content), while the remaining 30% must be equally divided between T=15% and A=15%.

Answer:

Explanation:

Answer: During competition, organisms that have favorable traits for this task will survive and are said to be selected. These organisms will reproduce and pass on those traits to their offspring. Thus, the frequency of organisms with those traits will increase

Explanation: In Darwin's theory on the mechanism of evolution, competition among living things is viewed as a major part of the “struggle for existence” and therefore as a basis for natural selection (Darwin 1872).

Answer:

Captive breeding program

Explanation:

A captive breeding program can be defined as the process of collecting wild specimen and allowing them to reproduce in an environment away from predation. This is an important part of saving endangered species. Specimens of such species are bred in zoos and similar facilities in order to build a healthy population. Sometimes, these species are successfully reintroduced back into the wild. Examples of animals that were successfully saved like this are the California condor, black-footed ferret, golden lion tamarin, and red wolf.

Red blood cell antigens determine your blood group

Answer: The antigens expressed on the red blood cell determine an individual's blood group. The main two blood groups are called ABO (with blood types A, B, AB, and O) and Rh (with Rh D-positive or Rh D-negative blood types).

Answer:

The cochlea is filled with two fluids (endolymph and perilymph), and inside the cochlea is the sensory receptor, the Organ of Corti, which contains hair cells, or the nerve receptors for hearing.

Have a good day

Mechanoreceptors are involved in hearing, which transmits the signals from external stimuli through mechanical ion-gated channels.

The organ of the Corti on the basilar membrane has hair cells that are involved in the sensory mechanism for hearing.

In the inner ear, there are six receptors (cochlea, two otolith organs, and three semicircular canals) which make a transduction unit consisting of hair cells.

In these receptors, external stimuli transmit the signal through the mechanically gated channel, external stimuli are touch, pressure, and hearing.

This processed signal to the brain by the neurons to hear the sound, and all the signal accumulate through the primary sensory receptors which are hair cells in the ear.

Therefore, mechanoreceptors are involved in hearing.

Answer:

A

Explanation:

Active transport is required for energy given to proteins in the phospholipid layer (Option c).

Active transport is a type of transport across a cell membrane that requires energy, usually in the form of ATP, to move substances (either molecules or ions) against a gradient of concentration.

Conversely, passive transport refers to the movement of substances across a membrane in favor of a concentration gradient, which does not require energy.

Active transport is mediated by transporter proteins known as carriers and/or pumps.

In conclusion, active transport is required for energy given to proteins in the phospholipid layer (Option c).

Answer:

"Up" or "against" a concentration gradient means from low concentration to high concentration. Moving in this direction requires some sort of energy input, such as active transport using ATP, or an electrical gradient, or something else.

Answer:

B

Explanation:

I did the test

Answer:

These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). In fact, the spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres.

Answer:

C The correct sequence of the transfer of information in most organisms is DNA to RNA to protein.

Explanation:

Gene expression involves the flow of information from DNA molecules to the formation of proteins. Information first flows from DNA molecules to RNA through a process called transcription.  Transcription is the first step of gene expression in which an RNA especially the mRNA is synthesized from a DNA molecule by RNA polymerase enzyme.  Then the synthesized mRNA is taken to the cytoplasm where it undergoes the translation process to form proteins.
