Which of the following is NOT true about matter in the biosphere?
a) Matter is transferred in one direction through the biosphere. b) Biogeochemical cycles transform and reuse molecules. c) The total amount of matter decreases over time. d) Human activity does not affect the movement of matter

Answers

Answer:

c) The total amount of matter decreases over time.

Explanation:

The statement 'the total amount of matter decreases over time' is NOT true about the matter in the biosphere (Option c).

The biosphere refers to the total of all ecosystems of the Earth.

The biosphere can be defined as a closed system in terms of matter because matter does not enter or exit.

In the biosphere, the total amount of matter remains constant over time, whereas the total amount of energy decreases over time.

This energy is lost in the form of heat when it spreads from the Earth's surface and outward into space.

In conclusion, the statement 'the total amount of matter decreases over time' is NOT true about the matter in the biosphere (Option c).

Family members have a widely varied genetic make-up that can be affected by specific mutagens.
Family members share the contagious mutagens that can be passed by close exposure.

Answers

Answer:

Family members have a similar genetic make-up that may make them predisposed to cancer.

Explanation:

Variation in certain genes can increase the risk of developing certain cancers. This is why certain cancers run in families. There are lots of examples where the risk factor is small, but in some cases, the risk factor is very large.

For example, mutations in BRCA1 are very highly linked to the risk of breast cancer. As a result, many women with mutations in this gene opt to get a mastectomy to reduce their chances of developing breast cancer.

As lactose approaches the active site of lactase, as shown in the image, which of the following occurs first?

The lactose molecule is broken into glucose and galactose.
Lactase shifts to its lowest free energy level to allow lactose to enter the active site.
Lactose creates a microenvironment as it approaches lactase to promote binding.
Temporary bonding occurs between the active site and the substrate, causing a conformational change.

Answers

Answer:

There is no image attachment, however, this question can be answered based on general understanding of enzymes. The answer is:

Temporary bonding occurs between the active site and the substrate, causing a conformational change.

Explanation:

Enzymes are proteinous molecules that acts as catalyst in biochemical reactions by speeding up the rate of reactions. According to this question, lactase is an enzyme that acts on lactose sugar and breaks it down into its monomeric unit (glucose and galactose).

All enzymes possess an active site, with which they bind to their substrate. In this question, the lactose (substrate) approaches the active site of lactase (enzyme), what occurs first is that a temporary bonding occurs between the active site and the substrate, causing a conformational change in the shape of the enzyme.

What is population distribution?

Population distribution is how the population of something, plants, animals, or humans is distributed in specific areas. It specifies where people live or where they are not living.

There are three types of population distribution:

Uniform dispersion - In this distribution, the population is uniformly or evenly distributed in the areas. Even distribution comes under this distribution.Random dispersion - there are no predictable patterns in this dispersion. They are randomly present anywhere.Clumped dispersion - This distribution shows the bunch or group of population is areas then there is no population, and then there is a a bunch of population in another place.

how does matter move from the hydrosphere into the biosphere explain in your own words

Answers

Water moves from a river (hydrosphere) into the air (atmosphere) by a process called evaporation. Carbon dioxide moves from your body (biosphere) into the air (atmosphere) by a process called respiration. Minerals move from rock (geosphere) into the soil (pedosphere) by the process of weathering.

Water mover form hydrosphere i.e river to biosphere i.e atmosphere by a process of  evaporation.Thus, we can say that matter is move from hydrosphere to biosphere.

What is hydrosphere and biosphere?

Hydrosphere:-

The hydrosphere is the collective mass of water which is found on under, or above the surface of earth. Although earth hydrosphere is 4 billions old. A planet's hydrosphere can be liquid, vapor or ice.

Biosphere:-

The region or area of surface where living organisms survive their life are called as biosphere. The biosphere is a narrow zone on the surface of the earth where soil, water, and air combine to survive life.

Evaporation:-

The process in which water or liquid converts into vapor is called as evaporation.  In the case of water it starts vaporization at 100 degree C.

So, we can say that the conversion of matter from hydrosphere to biosphere is successfully achieved by evaporation.

Therefore, Water mover form hydrosphere i.e river to biosphere i.e atmosphere by a process of  evaporation.Thus, we can say that matter is move from hydrosphere to biosphere.

·make their own food

Answers

Explanation:

·have cell wall

cell wall is present in plant and fungi due to protection

but not in animals due to locomotion mode of life

Fungi have cell walls characteristic which fungi share with plants but not animals, hence option C is correct.

What are the characteristics of fungi?

When compared to animals, fungi need prepared organic substances for energy because they are heterotrophic organisms without chloroplasts.

Fungi are eukaryotic organisms, just like plants, and have nuclei in each of their cells. Like plants, fungi lack a cell wall and vacuoles, however, they do have a material called chitin in their cell walls that plants do not. In numerous important respects, fungi are also similar to animals.

Eukaryotic, non-vascular, immobile, heterotrophic creatures are fungi. They could be filamentous or unicellular and spread spores to reproduce. The phenomena of generational alternation are seen in fungi.

Therefore, in comparison to plants, fungi have vacuoles and a cell wall.
