How do frogs and toads, as well as salamanders, typically protect themselves from predators?

by injecting venom into the predator using teeth

by crawling or hopping to a safe place

by squeezing the predator to suffocate it

O by rolling over and pretending to be dead

Answers

Answer:

by crawling or hopping to a safe place

Explanation:

Most Amphibians like frogs, road, salamander protect themselves from predator by hopping and crawling to a safe place because they have the ability to puff out and look bigger in the sight of the predator. They can also remain underneath in water quietly for a long time. For example frog secrete moisture which sometimes it is irritating to the predators and serve as a defensive mechanism.

What impact could artificially raising the carrying capacity have on the deer
population long term?

Answers

Answer:

Deer population increases.

Explanation:

Deer population increases if increasing occur in carrying capacity of an ecosystem by artificial means because more food, water, shelter and other resources are available to the deer due to increasing carrying capacity of an ecosystem. If food, water and shelter are available in large amount to the deer so they reproduce rapidly and increase occur in their population.

Consider an organism that has a dominant phenotype, is it possible to determine its genotype? explain your answer

Answers

Answer:

Yes, it is possible via testcrossing

Explanation:

The law of dominance has made it possible that a phenotype may be expressed without knowing the actual genotype (allele combination). This occurs when an allele is dominant over another allele (recessive), hence, the dominant phenotype can either be in a heterozygous or purebred state.

However, a way to discover the genotype of an organism that is portraying dominant phenotype is TEST CROSS. Test cross is the crossing of the unknown genotype with a recessive condition (will contain same recessive alleles).

After crossing, the offsprings will be used to determine whether the parent with unknown genotype is heterozygous or not.

- If the offsprings all exhibit the dominant phenotype, the unknown genotype contains the same dominant alleles e.g DD.

- If 50% of the offsprings exhibit a recessive phenotype, the unknown genotype is heterozygous e.g Dd.

What is the amplitude?

B. The distance between the two crests
C. The highest point in the wave
D. The lowest point in the wave

Answers

amplitude: the height of the wave as measured between the trough and the crest. so i think the answer is A?

The distance from the center of the wave to the crest or the trough, hence option A is correct.

What is amplitude?

It alludes to the greatest departure from equilibrium that an item in periodic motion may exhibit. As an illustration, consider how a pendulum moves through its equilibrium point (straight down) and then moves outward to its maximum extent.

Measure the largest displacement of a point in the wave's medium from its resting position to determine its wavelength. Measure the length of the wave's cycle, generally from peak to crest or trough to trough, to determine its amplitude.

Think about how a pendulum travels through its equilibrium point (straight down) and then goes outward to its farthest point as an illustration.

Therefore, the distance from the center of the wave to the crest or the trough, hence option A is correct.

a. Substitution
b. Insertion
c. Deletion

DONT CHOOSE A< B< C
I need each of those to have an answer. So if you dont know how to do it , dont say anyhting. I will give brainlist

Answers

Answer:

Given the sequence of bases of the RNA GGAUUC, the possible mutations would be:

a. Substitution: GGAUUC → GGAAUC

b. Insertion: GGAUUC → GGACCUUC

c. Deletion: GGAUUC → GG_UC

Explanation:

The fragment observed is recognized as RNA, due to the presence of uracil (U). The mutations observed in this fragment are derived from a mutated DNA molecule, which was transcribed into mRNA

Substitution is a molecular mutation that occurs when one nitrogenous base is changed to another in the DNA sequence.                              GGAUUC → GGAAUC   Mutated DNA: CCTTAGInsertion occurs when entire bases or segments are added to the original genetic material, resulting in a longer molecule.                                 GGAUUC → GGACCUUC     Mutated DNA: CCTGGAAGDeletion is a type of mutation where genetic material is lost, which can be nitrogenous bases or segments of the molecule.                                GGAUUC → GG_UC     Mutated DNA: CC_AG

Each of these mutations can have an effect on protein synthesis, affecting the structure or function of the final protein.

Smokers, alcohol abusers, overweight and obesity men are more
likely to have sperm which are?

Answers

Answer:

fewer in number.

Explanation:

A low sperm count also known as oligospermia can be defined as a medical condition which typically involves a man (adult male) having fewer than 15 million sperm per millilitre of semen.

Basically, low sperm count (oligospermia) is usually caused in men due to health and lifestyle factors such as smoking, alcohol or drug abuse, obesity, genetics, sexually transmitted infections (STIs), age etc.

Hence, smokers, alcohol abusers, overweight and obesity men are more likely to have sperm which are fewer in number i.e fewer than 15 million sperm per millilitre of semen.

Generally, a healthy or normal sperm motility ranges from over 20 million to 200 million sperm per millilitre of semen.
