What is the volume of a square pyramid with a base edge of 14 m and a slant height of 25 m

Answers

Answer:

length of base(l) = 14m

slant height (s)=25m

we know,

slant height(s)=√(l/2)^2 + h^2

or, 25= √(14/2)^2+ h^2

or, 25 = √49+h^2

or, 25^2 = 49+h^2

or, 625 = 49 + h^2

or, 625-49=h^2

or, √576 =h

h=24

Therefore vertical height (h)= 24m

Again,

Volume of square pyramid (v) = 1/3 L^2h

or, v =( 1/3) 14^2×24

or, v= 4704 / 3

Therefore, V= 1568 cubic meter.

Answers

B. because irruptive is when the growth goes up and cyclical is when the growth continuously keeps changing

When there is no pattern to a population's growth, it is known as stable. The correct option is B.

What is population growth?

The rise in the number of people on Earth is referred to as population growth. The majority of human history saw a relatively steady population size. Energy, food, water, and medical care, however, became more accessible and dependable as a result of innovation and industrialisation.

The predicted population expansion is due in part to factors like an increase in young, unmarried mothers, high fertility rates for specific ethnic groups, and a lack of access to contraception and sexual education.

When age-specific fertility and mortality rates are constant over a long period of time, there is a stable population growth.

Contrarily, an irregular population increase is one in which there is no structure and the population size behaves chaotically.

Thus, the correct option is B.

The four main forces that drive evolution are mutation, natural selection, genetic drift, and gene flow. All of these forces can cause a change in what?

Answers

Answer:

Allele frequencies

Explanation:

The only component that is transmitted from generation to generation is the genetic material (genes), the fact that an individual leaves more descendants implies that their genetic variants (alleles) will be more represented in the next generation. The frequencies of the different alleles will change from one generation to another, and this change will be irreversible when the set of genes in the population is considered, since it is highly unlikely that a previous configuration will be returned in all gene variants. Hence, from a population point of view, evolution is ultimately a cumulative and irreversible change in the proportions of different gene variants in populations. The agents that change the allele (or gene) frequencies of populations, that is, factors of evolution, are mutation, genetic drift, migration, and natural selection. Mutation is a factor that increases genetic diversity. Natural selection is the process by which the gene frequencies involved with certain traits vary from generation to generation, since some variants of the trait have a greater capacity than others to survive and produce offspring. The mutation rate of a gene or DNA sequence is the frequency at which new mutations occur in that gene or sequence in each generation. In each generation there is a gene raffle during the transmission of gametes from parents to children which is known as genetic drift. In the absence of gene flow, gene drift will also lead to local differences in allele frequencies.

Explain how a carbon atom from a CO2 molecule in the air can end up as a carbon atom in a protein in a plant cell

Answers

Answer:

Photosynthesis and metabolism are among the most complex areas in biology so given the nature of this forum I've kept the answers simple and brief.

Carbon is of central importance to all biological systems due to its special bonding properties allowing it to form various bonds with other atoms and produce a wonderfully complex range of molecules used by life.

In photosynthesis inorganic carbon in carbon dioxide gas is fixed to hydrogen to produce sugar, an organic molecule. In this case the carbon gains electrons so it is 'reduced' and this process requires energy in the form of light. Once in sugar form, the process can be reversed and the carbon can be oxidised back into carbon dioxide during cellular respiration, releasing energy.

So in photosynthesis, the carbon from carbon dioxide is reduced to form a sugar molecule. When transitioning to respiration, the carbon in the sugar is oxidised to form carbon dioxide again in the reverse reaction to photosynthesis.

The carbon is transferred between molecules through various intermediate steps during these processes, involving enzymes (biological catalysts) to assist in cleaving specific bonds at each stage. During cellular respiration (an energy release reaction) as the carbon is successively oxidised electrons are liberated that are used as part of the energy release. These electrons are captured or 'carried' by special organic molecules called NAD and FAD (reducing them) which in turn can then be oxidised to produce the universal energy currency of life: ATP molecules. ATP is a small bio molecule containing a high energy phosphorous bond that can be broken to release energy to do cellular work. It is used by all life that we know of and is the ultimate product of cellular respiration.

When Photosynthesis and metabolism are among the most complex areas in biology Then given the nature of this forum. Carbon is of central importance to all biological systems due to its special bonding properties allowing it to form various bonds with other atoms and also, produce a wonderfully complex range of molecules used by life.
