if all the green plants were removed from the community how might the flow of energy be effected

Answers

If all the green plants were removed from the community the flow of energy to both animals and humans would stop. Through photosynthesis, plants convert the suns energy into oxygen that living creatures need to survive. Plant also remove carbon dioxide from the air, which can be toxic at about one percent concentration.

How are bees vital to our ecosystem? Describe what could happen if bees were to disappear from ecosystem Earth and what the consequences would be. In general, use WHO, WHAT, WHEN, WHERE, and WHY “are bees” DYING off. Lastly, how could We as humans integrate Bee hives efficiency in our own society?

Answers

Answer:

They are pollinators.

Explanation:

Bees are vital to our ecosystem because they are pollinators and due to this pollination, these bees are responsible for the presence of trees, shrubs and other small plants etc. if bees were to disappear from ecosystem Earth then the whole world is adversely affected because trees can't produces fruits and seeds so after sometime animals die due to unavailability of food. Human activities are responsible for the death of these bees because human activities causes pollution which is not good for bees. We have to make a safe place for bees and grow as many flowers as you can in order to increase their population.

4. How does the cell membrane allow the cell to reproduce into two separate cells?

5. In the lab, small bubbles would merge with the larger bubbles. How does this property of cell membranes demonstrate how a vesicle can transport substances from one organelle to another?

6. Cells require molecules that cannot simply pass through the cell membrane. Explain how the cell can use proteins to transport these molecules across the cell membrane.

Answers

Explanation:

1)The cell membrane functions as a semi-permeable barrier, allowing a very few molecules across it while fencing the majority of organically produced chemicals inside the cell. Electron microscopic examinations of cell membranes have led to the development of the lipid bilayer model (also referred to as the fluid-mosaic model). The most common molecule in the model is the phospholipid, which has a polar (hydrophilic) head and two nonpolar (hydrophobic) tails.

2) simple diffusion across the cell plasma membrane. The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down the concentration gradient is , by simple diffusion.

3) some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic or however, because they are charged the polar, they can't cross the phospholipid part of the membrane without help .

4) during fission a copy of the DNA is made and attached to the cell membrane as well. As this cell elongate in preparation for fission, the two DNA copies are pulled apart two opposite ends of the cell. New membrane material is deposited between the two ends of the cell, and a new wall grows between them .

All camels are basically similar in structure. They have developed adaptations for coping with both heat and dehydration.
Which of the following does not benefit the camel as a means of preventing dehydration?

a.Camels can extract water from their solid wastes.
b.Camels' ears are lined with fur to keep out sand and other blowing matter.
c.Their kidneys are capable of concentrating urine to reduce water loss
d.Camels are able to locate water in any environment.

Answers

Answer: b

Explanation:

Camels ears are lined with fur to keep out sand and other blowing matter

The Cambridge family includes the unusually shaped Arabian camel (Camelus dromedarius), also referred to as the one-humped camel. This animal is perfectly suited to the harsh desert climate and high levels of heat stress. Thus, option B is correct.

What camels are adaptations for heat and dehydration?

Camels have evolved to survive in extremely hot and cold climates.In contrast to many other mammals, camels store the majority of their body fat in their humps, which allows for better thermoregulation. It makes it easier for them to release heat from their body in hotter climates. Camels rarely perspire.

Camels are ideally suited for desert survival. They have developed wide, flat feet to disperse their weight across the sand, among other adaptations. Thin fur everywhere to allow for rapid heat loss, and dense fur on the top of the body for shading.

Therefore, The kidney may be able to retain water if the generation of cholesterol is reduced. Camels produce pee that is highly concentrated, retaining the maximum amount of water.

How can you use genetics to study human inheritance?

Answers

Answer:

by analyzing how genes influence the development of phenotypic traits, i.e., by determining the association between phenotypic traits and changes in DNA sequence

Explanation:

Genetics is a discipline that studies how genetic variation, i.e., the variation in the Deoxiriibunicleinc acid (DNA) molecule, is associated with the transmission of heredity, and how the environment influences this process. The DNA is a molecule that carries the instructions to perform all metabolic functions (eg., reproduction, development, growth, etc). Thus, advancements in genetics enabled us to decipher how phenotypic traits pass from parents/ancestors to their offspring/descendence. Genes are segments of DNA that carry the information (genetic information) to determine each phenotypic trait. During reproduction, genes are passed from one generation to the next, thereby transmitting this information across generations.

Answers

Answer:

sexual reproduction occurs by cell division during mitosis to produce two or more genetically identical offspring. Sexual reproduction occurs by the release of haploid gametes (e.g., sperm and egg cells) that fuse to produce a zygote with genetic characteristics contributed by both of the parent organisms.

What are the products when a DNA molecule replicates?

A two molecules of DNA each made of a paired sequence of bases
B two molecules of DNA each made of a paired sequence of nucleotides
C two strands of DNA each made of a paired sequence of bases
D two strands of DNA each made of a paired sequence of nucleotides

(Its NOT c.)

Answers

The Answer is B because in DNA it is molecules

The products when a DNA molecule replicates are two molecules of DNA each made of a paired sequence of nucleotides. The correct option is B.

What is DNA replication?

A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication.

Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.

Before dividing, cells must copy their DNA. This promotes successful inheritance of genetic features by giving each daughter cell a copy of the genome.

The fundamental mechanism of DNA replication is similar across all organisms, making it a crucial operation.

Two DNA molecules, each consisting of a paired sequence of nucleotides, are produced when a DNA molecule duplicates.

Thus, the correct option is B.
