The given diagram describes that 2. Water molecules are too large to enter or leave the cell, so they remained where they were at the start of the investigation.

A cell is the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge.

Answer:

1. A rock that contains evidence of past animal or plant life is called a fossil.

2. Prehistoric  Woolly Mammoth have been discovered in permafrost in Alaska and Siberia.

3. Hardened tree sap can preserve animals in a substance called amber.

4. Fossils can be created by replacement using minerals such as silica, calcite, pyrite.

5. A  mold shows the original shape of the plant or animal.

6. A cast represents a  solid version of the original plant or animal.

7. Trails, tracks and burrows are examples of  trace fossils.

8. Some of the oldest fossils on earth are from ancient  worms crawling on the seafloor.

Explanation:

Fossils are known to be the remains of plants and animals which have been preserved and kept in rock. They are usually a shell, skeleton or plant fiber that has been buried.  Over time, they turned into rock.

Fossil amber are known to be fossil insects that are preserved in hardened tree sap. These insects and some small animal or plant that are found in these hardened tree sap were trapped in the tree.

Woolly Mammoth is known to be a closest extant relative to the Asian elephant. The appearance and behaviour of woolly mammoth are among the best studied in Siberia and Alaska.

Answer:

Catalase is an enzyme in the liver that breaks down harmful hydrogen peroxide into oxygen and water. When this reaction occurs, oxygen gas bubbles escape and create foam. Completely disinfect any surface that the raw liver touches during this activit.

Explanation:

hope this helps you a little have  a great day sir/mam

Catalase speeds up the conversion of hydrogen peroxide into water and oxygen by decreasing the reaction's activation energy. Thus option A is correct.

Catalase is a common enzyme present in all living organisms.

These are tetramer molecule consisting of four polypeptide chains, each of these chains are over 500 amino acids.

In mammal it is found in liver and contains four iron-containing heme groups that allow the enzyme to react with hydrogen peroxide.

In mammalian cell, Catalase involve in  decomposition of most toxic substance called hydrogen peroxide into less toxic products like water and oxygen.

It protect the cell from oxidative damage by reactive oxygen species.

The optimum pH and optimum temperature for the activity of this enzyme ranges from four and eleven depending on the species.

Thus option A is correct.

Answer:

1/2

Explanation:

This question involves a single Gene coding for fruit color in radish plants. The gene exhibits incomplete dominance where the allele for red radish (R) and the allele for white radish (W) forms a hybrid with a purple radish (RW).

If a purebred red radish (RR) is crossed with purebred white radishes (WW), purple radishes (RW) will be formed. However, when the purple radishes are self-crossed i.e. RW × RW, the following gametes will be produced- R and W.

Using these gametes in a punnet square (see attached image), the following offsprings will be produced in the following proportions:

RR - red = 1/4

RW - purple = 2/4 or 1/2

WW - white = 1/4

Hence, the chances of producing purple offspring when you cross two purple parents is 1/2.

Answer:

Symbiosis

both species benefit in this symbiotic relationship

Answer:

Natural gas

Explanation:

Answer:

The answer is Natural gas

Explanation:

Simple answer:

When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white. Warmer water temperatures can result in coral bleaching. ... This is called coral bleaching. When a coral bleaches, it is not dead.

More in depth explanation:

Exposure to higher (100 and 1000 µg l-1) diuron concentrations for 96 h caused a reduction in ΔF/Fm¹, the ratio variable to maximal fluorescence (Fv/Fm), a significant loss of symbiotic dinoflagellates and pronounced tissue retraction, causing the corals to pale or bleach.

Answer:

the last one is:

 In the process of meiosis, alleles separate and are added to the gametes in an independent manner. While each gamete (egg or sperm cell) therefore contains one allele for each gene, it's impossible to know which allele, because alleles segregate in a random manner. However, it's possible to calculate probabilities that the offspring will have a given allele using Punnett squares.

Explanation:

Crossing over process results in new combinations of alleles in the gametes (egg or sperm) formed, which ensures genomic variation in any offspring produced.

Chromosomal crossover, or crossing over, is the exchange of genetic material during sexual reproduction between two homologous chromosomes' non-sister chromatids that results in recombinant chromosomes.

This process, also known as crossing over, creates gametes that contain new combinations of genes, which helps maximize the genetic diversity of any offspring that result from the eventual union of two gametes during sexual reproduction.

Crossing over is an enzyme-mediated process, where the exchange of genetic material between non-sister chromatids of homologous chromosomes takes place.

Explanation:

Corporations and industries are responsible for a large percentage of  environmental pollution being witnessed in several regions of the world. The pollutions have negative consequences for the environment and the organisms living in it, including humans. Hence, formulating laws to regulate the amount of pollution that can be added to the environment is in the best interests of the public. Any person that fights against these laws is likely working in the interests of industries and corporations and not the public in its entirety.

Answer:

Fern

Explanation:

The plant discovered by the botanist is most likely a fern.

Ferns are referred to as seedless vascular plants. They do not produce seeds and they possess vascular tissues in the names of xylem and phloem. The xylem conducts water/mineral salts from the roots to the body of the plant while the phloem distributes manufactured foods from their sources to other parts of the plant.

Ferns also have independent gametophyte and sporophyte stages. The sporophyte produces haploid spores through meiosis which then germinates to the gametophyte. The gametophyte produces male and female gametes - antheridium and archegonium. The antheridium is motile and swims to meet the immotile archegonium during fertilization to produce the zygote which then divides mitotically to give the sporophyte.
