Ans.

Biological interactions or ecological interactions are defined as relationships that affect two organisms of same or different species living in a community. Different types of association are observed in different organisms.

Barnacles and whale show a type of symbiotic relationship, in which barnacles get benefit from association, without causing any harm to whale. This type of association is known as commensalism. Thus, option A). correctly matches with option 3). commensalism.

A stork and fish shows prey-predator relationship, where stork is predator that feeds on small fishes (preys). In this kind of relationship one species gets benefits, while other gets harm. Thus, option B). correctly matches with option 1). prey-predator.

A tick sucking the blood from an animal body shows a kind of symbiotic association, known as parasitism. The tick (parasite) lives inside inside or on the body of another organism (host) to get benefit and causes harm to the host. Thus, option C). correctly matches with option 2). parasitism.

Carbohydrates are the main sources of energy for most organisms. However, some carbohydrates can also be used as structural mate

Tema [17]

C:Cellulose is the primary structural carbohydrate found in plant cell walls. Only a few animals have a limited ability to digest cellulose. However, the fiber in the structural carbohydrates stimulates the animals' digestive systems, so stools stay softer and move more quickly through the intestinal tract. This helps to prevent constipation and encourages regular defecation.

Develop a hypothesis to explain why you think eurypterids developed legs even though they lived on the ocean floor.

expeople1 [14]

I think that since it lives on the ocean floor, at the deepest of the ocean. So anyway, the fin on the Eurypterids is still necessary but not that much, since they live on the ocean floor. Their movements mostly on the ocean floor. So fin would not help them "stick" to the floor. Also there are still gravity acts on the Eurypterids and the feet would help them move faster. Hope this helps.

Anuta_ua [19.1K]

The question is incomplete. Here is the complete question.

In horses, the Overo gene, Ov, produces a white splotch pattern on the coat. The overo phenotype is seen only when a horse has one Ov copy, Ovov. Horses with two Ov copies, OvOv, die soon after birth are called white overo because they are completely white. Horses with no Ov copies are solid colored, ovov.

The Leopard complex gene, Lp, shows incomplete dominance and controls white spotting. One Lp allele, Lplp, produces the leopard phenotype, in which there are spots everywhere. Two Lp alleles, LpLp, produce the fewspot phenotype, in which the horse is mostly white with colored spots.

A horse that is both overo and leopard is called pintaloosa, and these horses are spotted with splotches. A horse that is overo and fewspot is considered fewspot because the white areas from Lp is indistinguishable from the white from Ov.

Suppose that 16 pairs of pintaloosa horses have one offpring per pair. How many each phenotype would be expected? Determine the number out of 16 expected for each phenotype. Only count phenotypes of offspring expected to live past one week of age.

overo:

white overo:

fewspot:

Answer: Overo: 2

White overo: 0

Fewspot: 3

Explanation: Pintaloosa is a "combination" of overo and leopard, so the pair's genotype is OvovLplp.

To cross a pair, use Punnet Square and to facilitate, use the square for each characteristics:

Punnett Square For overo and white overo:

Ov ov

Ov OvOv Ovov

ov Ovov ovov

Analysing this Punnett square, notice that there are 2 individuals who will carry the genotype for overo (Ovov) phenotype. So, 2 out of the 16 pair will have an overo phenotype.

Since white overo is recessive (ovov) and doesn't survive past birth, there will be zero horses with that phenotype.

Punnett Square For leopard and fewspot:

Lp lp

Lp LpLp Lplp

lp Lplp lplp

From this square, notice that there are 1 individual who is fewspot. However, a horse that is overo and fewspot is considered fewspot, so for the 16 pair, 3 out 16 will be fewspot.

Describe the immediate effect of the neurotoxin on the number of action potentials in a postsynaptic neuron. Predict whether the

nikdorinn [45]

Answer:

Inhibit control over ions.

Explanation:

The immediate effect of the neurotoxin on the postsynaptic neuron is to inhibit control over ion concentrations across the cell membrane. The neurotoxin blocks nervous transmission at synapses which prevents the vesicles containing the neurotransmitter from fusing with the presynaptic membrane so the information does not transfer from one neuron to another and as a result the body is present at constant relaxation mode. The membrane potential of postsynaptic neuron will decrease due to neurotoxin.
