Why does climate change affect so many things?

Answers

Answer:

These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth's orbit and levels of carbon dioxide (CO2). Global climate change has typically occurred very slowly, over thousands or millions of years.

Explanation:

According to me there are several causes of climate change, but all the problems are based upon a major problem which is over population. Either it is deforestation, any kind of pollution, global warming or whatever it is, all these problems are inter-linked and all are due to increasing population.

Answers

Answer:

a)the outermost part of an animal cell that selectively allows things to pass through and come out.

b) the passing of water molecules from higher conc. to lower conc.

Answer:

(a) Semi-permeable membrane:

A semipermeable membrane is a membrane that only allows the movement of solvent molecules but restricts the movement of solute particles across the membrane.

(b) Osmosis:

The process of movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane is called osmosis.

When two nearby concentrations are different, materials will tend to spread out to equalize the concentration. For example, if you put a drop of food colouring in some water it will gradually spread through the whole water.

Explanation:

Answer:

homologous: have identical position, value, or structure

Fossils: In the oldest rocks area unit fossils of the best organisms and within the newest rocks area unit fossils of additional advanced organisms.

 

Explanation:

The evolution theory is supported by multiple sorts of evidence: homologous structures show common ancestry, whereas similar selective pressure will manufacture similar variations. analogous structures (beneficial features).

In the oldest rocks area unit fossils of the best organisms and within the newest rocks area unit fossils of additional advanced organisms. This supports Darwin's organic process theory, whereby straightforward life forms {progressively|increasingly|more and additional} evolved into more advanced. Proof of adolescence forms comes from fossils.

What goes on during interphase?

Answers

Explanation:

During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). ... Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA in preparation for mitosis, and conducts other "normal" cell functions.

Explanation:

During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase. During the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei. The cytoplasm is usually divided as well, resulting in two daughter cells

What is a disadvantage of using a space-filling model to show a chemical compound?

Answers

Answer:

Explanation:

The appropriate answer is 'space filling models do not identify the number and type of bonds'. A space filling model is one type of three dimensional (3D) molecular model used to represent molecules of different chemical compounds. The structure of this type of arrangement shows that, for example, two elements are bonded but it does not show if it is a single, double or triple bond.

Write down the functions of
1.microtubules
2.tripletsof microtubules

Answers

Answer:

Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells. Microtubules are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility

Centrioles are cylindrical structures that are made up of protein tubes called microtubules. Specifically, nine groups of three microtubules, known as triplet microtubules, are linked together to make the walls of the cylinder.

Hope it helps :)

Answer:

Microtubules have several functions. For example, they provide the rigid, organized components of the cytoskeleton that give shape to many cells, and they are major components of cilia and flagella (cellular locomotory projections). They participate in the formation of the spindle during cell division (mitosis).

triplet microtubules are linked together to make the walls of the cylinder.

Which of the following can be inferred from the genetic code?

A.All organisms have a common biochemical evolutionary origin.

B.Organisms can live without genetic code.

C.Four nucleotides.

D.Four nucleosides.

Answers

Answer:

A. All organisms have a common biochemical evolutionary origin.

Explanation:

Genetic code is the biological mechanism by which the DNA in our body is used to synthesize protein needed for growth and development. The genetic code comprises of all the possible 64 codons i.e. a group of three nucleotides that encode an amino acid.

One of the characteristics of the genetic code is that it is UNIVERSAL. This means that all known living organisms make use of the same genetic code and hence, this portrays that all living organisms share a common biochemical evolutionary origin.

Which is the difference between an antibiotic and an antiviral?

Answer:

There are no options in this question, the options are as follows:

A. Antibiotics build up immunity, and antivirals increase white blood cells.

B. Antibiotics treat the symptoms, and antivirals destroy the causing organism.

C. Antibiotics are in liquid form, and antivirals are in mist form.

D. Antibiotics treat patients who have Staphylococcus, and antivirals treat patients who have the flu.

The answer is D

Explanation:

Specific drugs are used to curb infection or diseases caused by specific pathogens. An infection can be caused by either bacteria, virus or fungi. Considering their different mechanism of infection, viral infections are treated with the use of ANTIVIRAL DRUGS while bacterial infections are treated with the use of ANTIBIOTICS.

According to this question, staphylococcus is a bacterial genus and hence, patients with staphylococcus can be treated with antibiotics while flu is a viral disease, hence can only be treated with antivirals.

Explanation:

Naturla selection is the survival and reproduction of individuals due to different phenotypes. The naturla selection represents a mechanism of evolution and changes in traits of species.

In order for natural selection to occur, organisms must :

have a variation that can be passed from one generation to the next.have differential reproductive success.

Natural Selection is a mechanism of evolution that occurs when there is a heritable variation for a trait and individuals with one version of the trait have greater reproductive success than do individuals with a different version of the trait.

In order for natural selection to occur, three conditions must be met:

There must be variation for the particular trait within a population.The variation must be inheritableIndividuals with one version of the trait must produce more offspring than those with a different version of the trait.

Thus,

In order for natural selection to occur, organisms must :

have a variation that can be passed from one generation to the next.have differential reproductive success.
