Explanation:

when water is frozen, it expands, something to do with anomolous expansion of water.

Water increases its volume when it becomes a solid.

Volume is a measure of occupied three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

The surface-area-to-volume ratio, also called the surface-to-volume ratio and variously denoted sa/vol or SA:V, is the amount of surface area per unit volume of an object or collection of objects.

If volume is the amount of 3-D space contained by a closed surface (e.g. the amount of space within a given cube, or cylinder, or any other 3-D shape), liquid volume is a way to measure an amount of liquid by describing it how much 3-D space it occupies.

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: Heterotrophs

Explanation: Heterotrophs, also known as other-feeders, can't capture light or chemical energy to make their own food out of carbon dioxide. Humans are heterotrophs. Instead, heterotrophs get organic molecules by eating other organisms or their byproducts. Animals, fungi, and many bacteria are heterotrophs.

plants reproduction can also reproduce sexually when their flowers are pollinated. They can also reproduce sexually when their flowers are pollinated. Roses produced through sexual reproduction have more genetic variation.

Reproduction in Flowering Plants occur both asexually and sexually, flowering plants or angiosperms, use the sexual mode of reproduction.

Reproduction in Flowering Plants occurs in the flower as  both male and the female gametes are present in it, various parts of flower involve in the process of reproduction.

There are four important steps in the reproduction of flowering plants. such as Pollination, Gametogenesis, Fertilization

The flower is a specialized structure where reproductive part of the plant, containing the male and female reproductive organs which facilitate fertilization.

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.

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:

Repairing ability and homeostasis causes the injured parts to return back to uninjured.

Explanation:

Due to repairing ability of levels of organization in the body helped the injured parts to return back uninjured. Yes, homeostasis that is present in and between cells help to return organ systems back to homeostasis or equilibrium state of the body. Our body has the ability to main homeostasis whenever some disturbance occur in the body. If this homeostasis not present our body, there will be no repairing of damaged occurs.

It should be noted that the repairing ability and homeostasis are vital as they cause the injured parts to return back to being uninjured.

Homeostasis simply means the process that living things use to maintain stability while they adjust to the conditions that are best for their survival.

The homeostasis that is present in and between cells is vital for returning systems back to the equilibrium state of the body. The body of an individual has the ability to maintain homeostasis whenever there is some disturbance that occurs in the body.

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:

1. Concentration of O2 in the alveoli must be more than that of the blood

2. Concentration of CO2 in the blood must be more than that of the alveoli

3. Movement does not stop (find the explanation below).

Explanation:

Gaseous exchange i.e. taking in of O2 and taking out of CO2, takes place in the alveoli/air sac of the lungs. However, the movement in and out of O2 and CO2 from the alveoli into the bloodstream and vice versa follows the principles of SIMPLE DIFFUSION. Diffusion is the process whereby substances move from a region of high concentration to a region of low concentration until they are evenly distributed. Based on this, the following will occur:

1. The concentration of O2 in the alveoli must be more than that in the blood in order for oxygen to enter the blood via diffusion.

2. The concentration of CO2 in the blood must be more than that in the alveoli in order for carbon dioxide to leave the blood and enter the alveoli via diffusion.

3. When the rate of diffusion is at equilibrium i.e. no net movement is occuring die to equal concentration of the substance on both sides, the substances begin to move in the opposite direction at an equal rate. Note that, at equilibrium, MOVEMENT DOES NOT STOP, however, there is an equal rate of movement.
