Answer:

exocarpo is synonymous with exocarp

endocarpo is synonymous with endocarp

mesocarpo is synonymous with mesocarp

semilla is synonymous with seed

Explanation:

In phase one, the plant's ovary begins to grow abruptly, this is where the embryo and endosperm affect their size, but if this ovarian growth is interrupted by an external factor, it determines the size of the future.

Then, the embryo and the endosperm could grow and undergo a process called sclerification, which is the hardening of the interior of the fruit, that is to say, the future formation of the seed or vulgarly called "pit". .

After this, the mesocarp, which is what is called the fleshy body or subglobose edible drupe, begins to grow.

The growth of the mesocarp is what gives the volume, weight and body to the fruit, so that after maturation it exceeds the strength of the branch and it falls from the tree.

Which force is the central causative agent of the cohesion-tension model of xylem transport?

PilotLPTM [1.2K]

The causitive agent of the cohesion-tension model of xylem transport is transpiration. During the process of transpiration, water vapor is lost from the stomata of the leaf. To replace this water, water from adjacent cells is withdrawn. The water molecules stick together due to cohesion and are transported upwards through the stem in the form of a stream.<span />

Cells grow in order for____ to grow and reproduce.

Ivanshal [37]

The best answer is organisms...

Cells only grow to replace other cells that die off and allow for the continued existence of the organism.

Please correct me if I'm wrong... :)

How do plants affect psychological and physiological responses? (lohr & relf, 2000) reduce stress induce a calming response

MrMuchimi

Plants affect physiological and psychological response in that, when plants are present, human beings they have no stress and they are more attentive more than when there are no plants.

Physiological response is termed as an automatic reaction which drives physical response to stimulus. For example, stress.

They respond to empathy and express of emotions in post stress communication.

Psychological responses are the reactions, symptoms, and signs which may lead to crisis or even to a traumatic event they respond to stimuli.

Which statement describes the relationship between a gene and an allele?

omeli [17]

Answer: option B) A gene can take different forms called alleles.

Explanation:

An allele is one of the two or more different forms of the same gene.

For example, a trait such as seed shape is represented expressed a gene, but with allele of "RR" (round seeds) and "rr"(wrinkled seeds) observed physically by the farmers.

Thus, the correct answer is that a gene can take different forms called alleles.

Each biological species is genetically isolated from other species. why do the species evolve independently?

Nookie1986 [14]

Species evolve independently possibly due to geographical isolations or behavioural isolations.

Geographical isolation includes the isolation of 2 groups of the same species. Since these 2 groups live in different locations, (e.g. a volcanic eruption resulting in a barrier between one side of an ocean and another side of the ocean), they will have different selection pressures in their different environments as well (e.g. one side of the ocean may have more sunlight and thus more underwater plantations than the other side of the ocean). Natural selection will eliminate those with disadvantageous characteristics (e.g. Fishes that only eat plants and nothing else on the side of the ocean with little plantations) with unfavourable alleles, and select for those with advantageous characteristics (e.g. Fishes are able to eat plants and other organic substances as well on the side of the ocean with little plantations) with favourable alleles.

Since the 2 groups have different selection pressures, natural selection will occur in different ways, selecting for and against different types of fishes with different types of alleles. Also, because of the barrier, they are not able to mate with each other, and there are no mixing of genes from one side of the ocean and the other side. They are genetically isolated. As genetic drift occurs over time, their gene pools become different from each other. Thus, they evolve independently.

Hope this helps! :)
