Lionfish are native to the tropical waters of the Indo-Pacific. What conclusions can be made about the impact of climate change on the range of lionfish and, therefore, on biodiversity?
Answer:
The correct answer is - Climate change has restricted the habitat of lionfish. It has become an endangered species, reducing biodiversity.
Explanation:
As we know it is native to the tropical waters of the Indo-Pacific region. The change in the climate will increase the temperature of the water and this will lead to the restriction of habitat which lead to the reduction in the population of the fishes. As they live in the tropical climate they are habitual of warmer water and can not survive the climate change.

Explanation:
A farmer grows several crops on a farm that has mostly shallow, sandy soil, meaning they have
a low water storage capacity and a high infiltration rate. Which of the following irrigation
methods would be the best suited for this farm?
Select one:
O a. Drip irrigation
O b. Surface irrigation
O c. Flood irrigation
O d. Furrow irrigation
For a sandy soil farmer should use drip irrigation method over surface irrigation.
Sandy soils have a low water storage capacity and a high infiltration rate. Therefore they need frequent but small irrigation methods, drip irrigation is most suitable method than surface irrigation.
In other irrigation methods such as Surface irrigation, Flood irrigation, Furrow irrigation water is discharged in quite large amounts but the soil lost it due to the high infiltration rate.
Therefore, for a sandy soil farmer should use drip irrigation method over surface irrigation.

Which line represents a reaction with an enzyme? (A or B)
Answer:
b
Explanation:
Answer:
B
Explanation:
Line b is closer to the enzyme, and that is making it closer to the reactants and the products. the course of reactants is going right, and the top line is going left, so there fore it is the bottom line, or line b.
In a certain species of mammals, gray fur (G) is dominant to white fur (8) and brown eyes (B) are
dominant to blue eyes (b). An animal with white fur and blue eyes is crossed with an animal that has
gray fur and brown eyes (GGBb). What trait will appear in all of the offspring of this mating?
Gray fur (G) trait will appear in all of the offspring of this mating.
This is because one parent has GG. Even if the other parent has gg, all the offspring will have Gg and G is dominant.
Dominant and Recessive traits:Dominant and recessive traits exist when a trait has two different forms at the gene level.
The trait that first appears or is visibly expressed in the organism is called the dominant trait. The trait that is present at the gene level but is masked and does not show itself in the organism is called the recessive trait.Learn more:

What does it mean for a trait to be dominant?
A.That it will be hidden by the recessive trait and not show up in the offspring.
B.That it will be the allele that will be shown in the offspring.
Answer:
B
Explanation:
Answer:
B. That it will be the allele that will be shown in the offspring
Explanation:
If something is dominant, that means it's stronger or more assertive. Think of an alpha wolf. It is dominant and is more assertive over its pack. The same is true for alleles (in most cases)

When the environment changes, organisms need to ______ or ____ to survive.
Answer:
adapt & evolve
Explanation:
When the environment changes, organisms need to adapt or evolve to survive.
How organisms adapt and survive to the changing environment?Natural selection is the process that results in this. Natural selection causes a species' nature to progressively change so that it can fit into the niche. A species can persist for a very long time before going extinct.
Environmental changes affect whether species are able to reproduce and survive, and this can result in population-level evolution. descent while being modified.
The process by which organisms adapt to their environment in order to increase their chances of surviving in that environment is known as evolutionary adaptation, or simply adaptation.

what is digestion? Starting from mouth, state the various steps involved in digestion
Answer:
The gastrointestinal system starts in the mouth. In reality, as soon as you eat the first bite, digestion begins here. Chewing splits the meal into sections that are easier to eat, and saliva combines with food to start breaking down the body into a shape that you can consume and use.
Explanation:
The mechanism of digestion can be divided into various phases, such as mouth, stomach, small and large intestine.
A complicated mixture of mechanical and chemical processes are used in digestion. The mechanism includes food intake and push, mechanical or physical digestion, chemical digestion, absorption, and defeat.

Gene:A gene is the basic physical and functional unit of heredity.Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. Alleles are forms of the same gene with small differences in their sequence of DNA bases.Every person has two copies of each gene, one inherited from each parent.Thus, option 4 is correct.

All frameshift mutations are equal
Answer:
All frameshift mutations are equal
Explanation:
Frameshift mutation is a type of mutation caused by insertion or deletion of nucleotide base(s) in a genetic sequence causing that sequence to be read in a different way from what was originally planned.
The bases in the sequence of a gene is read in three's (codon), however, when one or more bases is added (insertion) or removed (deleted), the reading frame is altered causing the sequence to be read in a completely different order that can result in a protein that is non-functional.
However, FRAMESHIFT MUTATION is so potent that it affects the sequence no matter where it occurs. In other words, the effect of all frameshift mutations are equal.
