Answer:

The proper matching is given below.

Explanation:

Predation Typical plant defence include(thorns,sticky substances) and chemicals(toxin,bad tastingchemicals) adaptation.

Competition When individuals fight for a common resource,the weaker one experience loss or affected adversely.

Disease pathogens can be transmitted to host by direct contact between hosts o through soil,water,air or any other surface.

symbiosis: This interaction is of three types: mutualism, commensalism, and parasitism. Symbiosis is an interspecific ecological interaction, that is, between organisms of different species, occurring in a compulsory and harmonious manner, allowing reciprocal advantages for the species involved. This association is permanent, causing dependence indispensable to the survival of the parties, and can no longer detach from each other. It can be classified as utilitarianism, commensalism and parasitism.
competition: When individuals fight for a common resource, the weaker ones experience loss or are affected adversely. Competition is a disharmonic ecological relationship that can involve individuals of different species (interspecific), promoting competition for one or more environmental resources: water, food, light and physical space, as well as between individuals of the same species (intraspecific). In addition to other resources, there is also a dispute between specimens of the same gender (male-male feud), seeking reproductive partners able to proliferate fertile descendants.
diseases : Pathogens can be transmitted to a host by direct contact between hosts or through soil, water, air, or any other surface. Diseases are disorders that alter the activities of some organ or even the whole organism, usually giving rise to unpleasant signs and symptoms. The causes are most diverse and can be triggered by pathogenic organisms such as viruses and bacteria, genetic problems, emotional factors and in some cases completely unknown factors.
predation: Typical plant defenses include physical (thorns, sticky substances) and chemical (toxins, bad-tasting chemicals) adaptations. Predation is an ecological relationship that occurs between individuals of different species and is therefore interspecific. In this case, only one of those involved benefits, so many authors classify it as an inharmonious relationship. Some plants are predatory (feed on small insects) and may have some defenses such as thorns, sticky substances, toxins, among others).

Ipatiy [6.2K]

Answer:

tentatively group it with birds and speculate that the trait shared only with bats is a derived rather than an ancestral trait with bats.

Explanation:

The scientist after his observation should tentatively classify this organism with birds and the the second end of calculating the other morphological traits which makes it possess the likely bat traits to be ancestral.

According to scientists, most widely used modern systematic practice

depends upon the assumption that a change from character in one species

to character occurs once and once only in the evolutionary process and that this process is irreversible so that it never returns.

In this scheme, there are no independently derived parallel evolutionary changes,

nor convergences from a variety of states to a single one. Therefore, when two organisms share a

character state different from other species, it is because they are more closely related to each other through a recent common ancestor than they are to other species.

Also using the parsimony principle, a scheme of common ancestry for all the species is derived that uses all the characters that have been observed.

devlian [24]

Answer:

C: competitive exclusion

Explanation:

<em>The competitive exclusion principle states that organisms living in the same community while competing for the same resources cannot coexist at a constant population rate. </em>

Once some of the species within the community get a slight competitive edge over other species, they become dominant and this might lead to the extinction of the weaker species in the long run.

<u>In the experimental plot, the removal of sea stars provided mussel and barnacle with a competitive advantage over other species within the community (sea stars are predators of mussels and barnacles). This led to the dominance of mussel and barnacle and the eventual extinction of other species within the experimental plot as compared to the control plot.</u>

The correct answer is C.

Answer: Option B.

Precise but inaccurate.

Explanation:

It is precise because the measurement taken with well incremated tool reflect how close it is to the actual value i.e it has the quality of been exact but diet to the missing of 4.0 centimeter because a hungry beaver made a snack of it earlier that day the measurements will be INACCURATE because it does not conform with the result of the standard or correct value to be gotten.

If a homozygous black bull is mated with a homozygous white cow and the calf is gray, this could be an example of ___________. H

givi [52]

Answer:

Incomplete dominance

Co-dominance

Explanation:

Gregor Mendel discovered the principles that governs heredity, in which one of them is that an allele called DOMINANT allele, is capable of masking the expression of its variant allele called RECESSIVE allele in a heterozygous state. However, there has been genetic scenarios contrary to this his LAW OF DOMINANCE.

One of those Non-mendelian pattern of inheritance is a phenomenon called INCOMPLETE DOMINANCE, where an allele does not mask the expression of another completely, instead their combined state produces a third intermediate phenotype that is different from both parents. This is the case of the homozygous black bull mated with a homozygous white cow to produce a grey calf. The grey phenotype is an intermediate phenotype of both the black and white colours that forms due to incomplete dominance.

Another genetic scenario is called CO-DOMINANCE, where one allele is neither dominant nor recessive to the other allele, but instead both phenotypes becomes simultaneously expressed in the heterozygous offspring. In this case, the black bull and white cow were mated to form a heterozygous calf with both black and white spots.

Rosa drew a diagram to compare substitution mutations and insertion mutations.

djverab [1.8K]

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>

$\huge\boxed{Option A}$

<h2>_____________________________________</h2><h2>Mutations:</h2>

Mutations are the changes produced in the nucleotide sequence of the genome.

There are four main types of mutations

Substitution

Insertion

Deletion

Duplication.

<h2>_____________________________________</h2><h3>DELETION:</h3>

A small segment of chromosome mat be missing. This condition is known as deletion.

For example, Normal chromosome has A B C D E F G. If deletion mutation occurs then mutated chromosome has A D E F G and B C got deleted.

<h2>_____________________________________</h2><h3>DUPLICATION:</h3>

In this condition, a part of chromosome present in exec ess to the normal chromosome.

For example, Normal Chromosome has A B C D E F G. If duplication mutation occurs, then mutated chromosome had A B C B C D E F G and B C is duplicated.

<h2>_____________________________________</h2><h3>SUBSTITUTION MUTATION:</h3>

Substitution is a type of mutation where one base pair is replaced by a different base pair.

For example, in the sequence CAAGT, if C replaces G, it is a substitution mutation.

<h3>INSERTION MUTATION:</h3>

In genetics, an insertion is the addition of one or more nucleotide base pairs into a DNA sequence.

For example, in the sequence CAAGT, if extra base G gets inserted after C, the new sequence would be CGAAGT.

Both substitution and insertion mutations change the position of nucleotide thus, the type of amino acid.
