Answer:

Sexual selection

Explanation:

It is sexual selection because it is a type of natural selection in which an organism or organisms acquire traits which help the individual to be choose as a mating partner or to have preference for a mating partner or for competition among one sex organisms in which a traits succeed.

Sexual selection can be intrasexual or or intersexual. Intrasexual is is competition between one sex of the same organism and intersexual is between sexes of different organism.

All of the above

Explanation:

Numerous virus can survive in extremely hot, freezing, extremely acidic, or extremely salty settings. Additionally, the viruses that infect such bacteria must be able to maintain their infectivity under adverse circumstances. Thus, option A, C, D is correct.

Because they lurk inside cells, viruses present a significant challenge to the immune system of the body.

Antiviral drug resistance may appear as chronic or escalating viremia or illness despite treatment, due to prolonged antiviral drug exposure and continued viral replication brought on by immunosuppression.

When a virus ceases responding to an antiviral drug, it is said to have developed antiviral resistance. Antiviral medications become ineffective or altogether useless as the virus evolves.

Therefore, virus are resistant.

Answer:

evolution of human works

Explanation:

The cell theory states that all living forms are composed of cells. These cells are the basic structural units of all organisms and they evolved from pre-existing cells present in primitive living forms. From a biological point of view, the evolution of cells is similar to the evolution of human works, which were during the beginning of human civilization less specialized than in modern times. Likewise, somatic cells present in evolutionary recent multicellular organisms are capable of carrying out more complex functions than primitive cells present in unicellular organisms.

Answer:

Although animal and plant cells are surprisingly similar, most of the difference between them is in their organelles. For example, plant cells have all the organelles found in animal cells plus:

Answer:

depth of light penetration

Explanation:

light is important in marine habitat, the distribution of organism, density and the type of organism is determined by the depth of light, the energy and how well the light can travel because most of the organism depends on light.

Green Plants, some algae and cyanobacteria survive through the production of their own food via photosynthesis. Photosynthate produced through photosynthesis is what is transported from area of production to other plant part where it is needed.

Photosynthesis can not be achieved without light penetration because light is what supplies the energy needed for the reaction.

Marine habitat refers to the distribution of organisms, plants, and aquatic animals in the oceans, seas, lakes, and ponds.

The factors such as oxygen demand and light penetration play a crucial role in determining the type and distribution of organisms in the different regions of the habitat.

Light penetration affect the marine ecosystem as:

Thus, light penetration plays a crucial role in determining the variety and distribution of organisms at different depths.

Minerals are the building blocks of rocks. They can be all one type of mineral, such as sandstone, which is made of sand, or they can be made of a variety of minerals, such as granite.

The Earth's crust is made up of rocks, which include the surface forms we see every day.

The particles in a solid are extremely attracted to one another. They are close together and vibrate in place, but they do not move past each other.

Rocks are classified into three types: sedimentary, igneous, and metamorphic.

Each of these rocks is formed by physical changes that occur as part of the rock cycle, such as melting, cooling, eroding, compacting, or deforming. Sedimentary rocks are formed from fragments of other rocks or organic material.

Thus, the correct option is a.

Answer:

This is because Carbon has four valence electrons (tetravalent) which gives it the ability to form up to four bonds differently with different elements/compounds. This gives rise to the creation of lots of compounds.

Carbon as an element also has atoms which fits into most substances thereby creating different possible compounds with others such as in carbohydrates, proteins, lipids etc. This is what makes Carbon an essential element for life.

Answer:

1. gravel of the sand: a part is dissolved and the remainder is grouped at the bottom of the beaker.

2. drop of sunflower oil: It is not absorbed and heaps on the surface of the water contained in the beaker.

Explanation:

Gravel of the sand is a polar substance. This means that this substance has the ability to dissolve and mix with water in a system in which both were placed together, such as a beaker, for example. However, the beaker limits the amount of water, which limits its ability to dissolve polar substances. Therefore, depending on the quantity, the gravel of the sand, when placed in a beaker with water, will dissolve, in parts, what is not dissolved will accumulate in the bottom of the beacker, because the gravel of the sand is denser than the water.

With the drop of sunflower oil the exact opposite happens. This is because drops of oil are nonpolar substances, which means that they do not have the ability to be dissolved in water. This means that when dropped into the beaker with water, the drop of sunflower oil will not dissolve, but will pile up on the water surface, because it is less dense than water.

Answer:

The correct answer is - chloroplasts

Explanation:

Plants or autotrophs contain exceptional organelles considered chloroplasts that traps light and use it to use carbon dioxide and water into sugar and oxygen. Living organisms without chloroplasts can not make their own food.  

Chloroplasts look like oval, flat circles. Like mitochondria, they also have two membranes. The whole organelle encased by the outer membrane. The inner membrane contains stroma, a thick fluid, which makes up the vast majority of the chloroplast's volume. Dispersed all through the stroma are piles of empty plates called grana that contain chlorophyll, which traps sunlight based on the intensity for use during photosynthesis.

All forms of life employ the same genetic code

Explanation:

The genetic code refers to the set of rules that facilitates the translation of nucleotide sequences into amino acids sequences (proteins). mRNA is read in a group of three nucleotides called CODON, which specifies a particular amino acid. The totality of all codons makes up the genetic code.

However, one of the characteristics of the genetic cos is its UNIVERSAL nature. The genetic code is said to be nearly universal meaning that the genetic code is the same in almost all living organisms with few exceptions. For example, AUG codon encodes Methionine amino acid in all forms of life.

Hence, All forms of life employ the same genetic code is TRUE. Note that, tRNA and rRNA are other types of RNA found in living systems. Also, liver cells are diploid i.e. has two sets of chromosomes. Lastly, interacting organisms affect their environment

All the forms of life employ the same genetic code.  

• It is true that all the forms of life exhibits the same genetic code, however, they do not possess similar genome.  

• The set of rules used by the living cells is known as the genetic code.  

• It is used to translate information encoded within the genetic substance, that is, mRNA or DNA sequences into the proteins.  

• The genetic code is greatly identical among all the organisms and can be articulated in a simple table with 64 entries.  

Thus, the correct statement is that all the forms of life employ the same genetic code.

layers of cell membranes- micro villi

Explanation:

They are similar to cilia but shorter in  length and diameter.They have average diameter of micrometer with average length of 2 micrometer

These are layers of cells membrane which protrudes or extended  on the epithelial lining of the  small intestine.They are microscopic in  structure,and their major function is to increase the surface area of the small intestine for absorption of digested food substances. Therefore reducing volume while aiding the rapid movement of the digested food into the bloodstreams.

Aggregate of micro villi is called brush border on the surface of the small intestine. Their activity with the villi aids the increase in the surface area which leads to absorption of food substances
