Answer:

Explanation:

now you have two mixtures of different solute concentrations. In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic, and the solution with the lower solute concentration is hypotonic. Solutions of equal solute concentration are isotonic.

The cell cycle phase that occurs immediately following cytokinesis is the interphase, which is in Option D because the interphase consists of the G1, S, and G2 and is constitutively called the preparatory phase.

The cell cycle consists of the interphase and the division phase, and in the interphase, the cell spends most of the time preparing itself for the cell division and consists of the G1, S, and G2 phases. Following the interphase, the cell enters the division phase, which is mitosis or meiosis, and divides, with the daughter cells potentially entering the cell cycle via the interphase.

Hence, the cell cycle phase that occurs immediately following cytokinesis is the interphase, which is in Option D because the interphase consists of the G1, S, and G2 and is constitutively called the preparatory phase.

Answer:

(x - 1)(x - 2)(x + 3)

Explanation:

f(x)=x3-7x+6 Since (a + b + c + d = 0), then f(1) = 0 --> one factor if (x - 1).

After division -->

f(x)=(x-1)(x2f2+x-6). The trinomial in parentheses can be factored.

Find 2 numbers knowing sum (1) and product (-6). They are -2 and 3.

Therefor, f(x)=(x-1)(x-2)(x+3)

Explanation:

The difference in the size of both rats are due to genetic and environmental because rats of both location increased in size which eats a lot of food as compared to those rats which eats balanced diet. This is due to the environment while on the the other hand, due to difference in genetics, New York rats grew larger than California rats of your friend which eats large number of food. So we can say that both genetic and environmental factors affect the rats size.

Answer: Chemoautotrophs like algae and plankten are able to use chemosynthesis for thier food.

So maybe it's autotrophs since they don't eat plant's or meat.

Answer:

The first question is the C and second is E

Explanation:

Answer:

D

Explanation:

The statement provides the strongest explanation for the trends in the two populations is predator-prey relationships act as density-dependent limiting factors on both predators and prey. Hence option D is correct.

Predator is defined as an organism that mostly hunts and consumes other organisms for food. The term "predator" refers to a species that hunts and eats specific other organisms. The animals that predators consume are referred to as prey.

Predator-prey interactions and prey-predator interactions are both crucial density-dependent population controls. The other population's size determines how each population changes in size.   When the population density reaches a particular point, a density-dependent limiting factor takes effect. Competition, parasitism, and disease are other instances of density-dependent limiting variables.

Thus, the statement provides the strongest explanation for the trends in the two populations is predator-prey relationships act as density-dependent limiting factors on both predators and prey. Hence option D is correct.

Answer:

The substrate molecules are entering the cells, so no product is made yet.

There is sufficient substrate, so the reaction is proceeding at a maximum rate

As the substrate is used up, the rate decreases (the slope is less steep)

The line is flat because no new substrate remains and thus no new product appears

Explanation:

First the substrate molecules enters in the cell and no product is produced because the reaction is not started yet. When the reaction starts, the substrate is in large amount while on the other hand, the amount of product is low. As the reaction proceed forward, concentration of substrate is lowering and concentration of product is increasing. When all the substrate used up, so no new product is formed.

Answer:A) Patau Syndrome (Trisomy 13) causes intellectual and physical disability, such as underdeveloped eyes, extra fingers/toes, heart defects. Survival beyond the first year is uncommon.

B)

Explanation: Trisomy (or aneuploidy in general) can result when chromosomes to do not separate correctly during mitosis or meiosis. In meiosis, non-separation of a chromosome pair results in a gamete with two copies of the chromosome (and consequently one gamete lacking the chromosome.

At fertilisation the embryonic cell will have three copies of the chromosome (and an embryonic cell with one copy only). These are serious mutations, many of which are non-viable and usually abort spontaneously. Others results in abnormal development and poor survival rates. Only one autosomal trisomy (21) and sex chromosome trisomies (XXX, XXY etc) result in babies that survive into adulthood, albeit with physical and developmental abnormalities (trisomy 21 abd trisomy X). Only one monosomy (XO) is viable.

Other mutations can be less inimical, and may not result in any variation from normal. Mutations in genes coding for proteins or ribosomes may result in potential loss of function. As there are two copies of each gene, the mutated gene is paired with a normal gene and if that is expressed there will be no loss of function.

There are cases where the mutated gene is dominant it will change the phenotype. An example is Marfan Syndrome, an autosomal (chromosome 15) dominant mutation resulting in connective tissue abnormalities and long bones.

An autosomal recessive mutation is not expressed but is carried. If both parents are carriers, the probability of offspring to be doubly recessive and have an altered phenotype is 25%. Cystic fibrosis is an example.

A third possibility is where two alleles are co-dominant. An example of this is sickle cell disease. Consider the three allele pairs SS, Ss and ss.

Those with ss have sickle cell anaemia, a painful and debilitating condition. Those with SS have normal blood cells. Those with Ss have sickle cell trait, which has some mild deficits because a proportion of blood cells are abnormal.

Answer:

B.sea floor spreading

Explanation:

The creation of new crusts at the middle of the mid- ocean ridges is also sea floor spreading.

The process of sea floor spreading entails the creation of new crusts at the margin of the oceanic crusts.

Basaltic materials from the subsurface upwells to the surface.

They cool and solidifies to form new crusts. The old crust is moved behind and away from the margin. This way, sea floor is formed and it spreads in like manner.

At this margin sea floor is created and at a convergent margin, it is destroyed.

Answer:

crossing over

Explanation:

During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.

Genetic variation can occur during meiosis because of the process of crossing over.

Crossing over is a cellular process that happens during meiosis when chromosomes of the same type are lined up. When two chromosomes one from the mother and one from the father line up, parts of the chromosome can be switched.

Crossing over is an enzyme-mediated process, where the exchange of genetic material between non-sister chromatids of homologous chromosomes takes place. It occurs at the pachytene stage of prophase I of meiosis.

During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material.

Answer:

See the answer below

Explanation:

Autotrophs are organisms that have the capacity to manufacture their foods from freely available inorganic products. There are two types of autotrophs

1. The photosynthetic autotrophs: these are green plants and blue-green algae that possess chlorophyll. The chlorophyll is used to trap radiation from the sun in the presence of water and carbon dioxide to manufacture carbohydrates which serve as their primary foods.

[tex]6CO_2 + 6H_2O + sunlight --> C_6H_1_2O_6 + 6O_2[/tex]

2. The chemosynthetic autotrophs: these are usually bacteria that make use of energy from inorganic chemicals (such as hydrogen sulphide, iron sulphide, etc) to reduce carbon dioxide and produce carbohydrates in the process.

[tex]CO_2 + 4H_2S + O_2 -> CH_2O + 4S + 3H_2O[/tex]

Photosynthesis is quantitatively more important to life on earth because green plants form the base of several food chains. The energy locked in the carbohydrate produced during photosynthesis is important for other lives in the ecosystem and this is passed on through the various levels in the food chain. Also, the by-product of photosynthesis, the oxygen, is important for the survival of most life on earth who depends on oxygen for respiration. Chemosynthesis only occur in habitats where the radiant energy of the sun is lacking, such as hydrothermal vents.
