Answer:Integral proteins

Explanation:

Answer:

Explanation:

Available data:  

The genetic distance = recombination frequency x 100 expressed in map units (MU). One centiMorgan (cM) equals one map unit (MU).

We can use the provided map with the distances between genes to predict the occurrence of any kind of recombinant gamete.  

We know that there is a probability of a simple crossing over to occur between genes A and B, or between genes B and C. And we also know that there is a probability of double crossing-over occurrence.

We can get the probability of the double-crossing over by multiplying the recombination frequencies between A-B and B-C. So,

DCO prob = recombination frequency A-B x recombination frequency B-C

                 = 0.1  x  0.03 = 0.003 = 0.3%

DCO prob = 0.3%

According to this, we would expect to find

Now we need to know what are the probabilities of getting a simple crossing-over, SCO. We already have the genetic distances between genes. 10 cM equals 0.1 of recombination frequency, and 3cM equals 0.03 of recombination frequency. However, we can not estimate the probabilities of simple crossing over using only this information, because this data is including the probabilities of the double crossing-over occurrence. So we need to substrate this percentage.    

SCO prob A-B = 0.1 - 0.003 = 0.097 = 9.7%

SCO prob A-B = 9.7%

we would expect to find

SCO prob B-C = 0.03 - 0.003 = 0.027 = 2.7%

SCO prob B-C = 2.7%

we would expect to find

The total Crossing-over probability, TCO, is then the sum of all the crossing over probabilities,

TCO= SCO A-B + SCO B-C + DCO

TCO prob = 9.7% + 2.7% + 0.3%

TCO = 12.7%

1s orbital

Explanation:

The electron has to go into the first energy level, in the 1s orbital. Helium, with two protons, will have two electrons. These are placed one at a time into the 1s orbital. This makes helium a very contented atom.

what is the question? I can't see.

Answer:

Hydrochloric acid  Prepares protein for  digestion  (denaturation)  Activates enzymes  and  “Disinfection”

Pepsin (an enzyme)  Begins protein  digestion

Gastric lipase  Some lipid digestion

Gastrin (hormone)  Stimulates gastric  secretion and  movement

Intrinsic factor (a  glycoprotein)  Needed for  absorption of vitamin  B12

Explanation:

Answer:

cellular respiration is a process that needs oxygen, so when oxygen is not present, they do not happen, but there is glycolysis, which doesn't need oxygen. the process of glycolysis produces 2 ATP and that is what is needed, so to continue glycolysis, the cells go through fermentation.  

Explanation:

THE ANSWER IS FERMENTATION!!!!

Answer:

If cellular respiration does not occur, then the level of oxygen present in the cell will get decreased as a result cell can die due to lack of oxygen. This is because cellular respiration provides the energy necessary for cellular activities.

Explanation:

they chose the best tomatoes to make even better ones

Breeding tomatoes to increase fruit size is an example of selective breeding. Therefore option A is correct.

Selective breeding, also known as artificial selection, involves the intentional breeding of plants or animals to promote desired traits. The process typically involves selecting individuals with specific characteristics and breeding them to pass on those traits to the next generation.

In the given options, breeding tomatoes to increase fruit size is an example of selective breeding. By carefully selecting tomato plants with larger fruits and allowing them to reproduce, breeders can gradually enhance the fruit size of future generations.

This process relies on natural genetic variation within the tomato population and human intervention to guide the breeding process toward the desired outcome.

Explanation:

Answer:

is a chemical bond between two non-metal atoms. Like Hydrogen, Oxygen, Carbon are just few.

There is a covalent bond between the oxygen and each hydrogen in a water molecule (H 2 O). Each of the covalent bonds contains two electrons, one from a hydrogen atom and one from the oxygen atom.

Explanation:

Water or Co2 is a covalent bond that be either polar which has a negative charge and positive charge like water that has one negative oxygen and two positive hydrogen. and non polar like Carbon bonding with carbon is both positive.

Explanation:

All of the other options go against actual facts and the laws of biology

The hydrogen bond is responsible for many of the anomalous physical and chemical properties of compounds of N, O, and F. In particular, intermolecular hydrogen bonding is responsible for the high boiling point of water (100 °C) compared to the other group 16 hydrides that have much weakerhydrogen bonds

Explanation:

Hydrogen bonding is primarily responsible for the high boiling point of the water. Thus, the correct option is B.

Hydrogen bonding is an interaction which involves a hydrogen atom that is located between a pair of other atoms such as nitrogen, oxygen, and fluorine which have a high affinity for electrons, and such a bond is weaker than an ionic bond or a covalent bond but are stronger than van der Waals forces and dispersion forces.

Hydrogen bonding is primarily responsible for the high boiling point of water solvent. Hydrogen bonding is a strong affinity. Hydrogen bonding is created when a hydrogen atom is bonded to an electronegative atom by approaching a nearby electronegative atom.

Therefore, the correct option is B.

Explanation:

Diffusion does not require energy. It's depends on the concentration gradient of the two molecules.

Diffusion is such an efficient process for all cells because it does not require energy. Thus, the correct option is A.

Diffusion may be defined as the migration of substances from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.

Diffusion does not require any type of energy for the movement of ions, molecules, or substances. It is a very feasible form of migration of substances.

Diffusion is a type of passive transport and hence takes place in a dropping manner without any expenditure of energy.

Therefore, Diffusion is such an efficient process for all cells because it does not require energy. Thus, the correct option is A.
