The options that scientists might think of to make up dark matter are as follows:

Thus, the correct options for this question are A, B, and D.

Dark matter may be defined as the type of particles that do not absorb, reflect, or emit light significantly. Due to this, they cannot be exposed by visualizing electromagnetic radiation. The materials of dark matter can not be examined directly.

According to the context of this question, dark particles considerably include weakly interacting massive particles along with the part of black holes and massive compact halo objects. Hypothetically, it is believed that approximately 85% of the matter in the universe accounts for dark matter.

Therefore, the correct options for this question are A, B, and D.

Answer:

Because the Earth rotates through two tidal “bulges” every lunar day, coastal areas experience two high and two low tides every 24 hours and 50 minutes. High tides occur 12 hours and 25 minutes apart. ... This occurs because the moon revolves around the Earth in the same direction that the Earth is rotating on its axis.

The two bulges created by the Moon align with the number and frequency of tides for each coastal city by the fact that the coastal cities experienced two consecutive high and low tides within the time interval of 24 hours and 50 minutes.

Tidal bulges may be defined as a type of natural phenomenon that significantly involves the gravitational attraction between the moon and the Earth provoking the water in the oceans which is present in a fluid state and mobile in nature.

These attributes force the water to be pulled toward the moon and stimulate the production of bulges. And due to the revolution of the earth on its axis changes the location of the water.

The process of tidal bulges accomplished the consistent revolution of the moon around the earth with respect to the rotation of the earth on its axis in the same direction.

Therefore, the coastal cities experienced two consecutive high and low tides within the time interval of 24 hours and 50 minutes.

Answer:

What are centrioles and centrosome?

Within the cell, a centrosome is a structure that organizes microtubules during cell division. Each centrosome contains “paired barrel-shaped organelles” called centrioles and a “cloud” of proteins referred to as the pericentriolar material, or PCM. They also enable movement of other organelles within the cytoplasm

Explanation:

Answer:

a centrosome is a structure that organizes microtubules during cell division. Each centrosome contains “paired barrel-shaped organelles” called centrioles and a “cloud” of proteins referred to as the pericentriolar material, or PCM.

Centrioles are made up of short lengths of microtubules “arranged around a central cavity.” Each centriole is around 500 nm long and 200 nm in diameter. The function of centrioles in animal cells is to organize the PCM to aid in microtubule formation.

Evidences that support the theory of evolution;

1. COMPARATIVE ANATOMY;

This is done to compare the anatomy structures of organisms to check the adaptive changes they have undergone through time. The similarities and differences of different body structures of different organisms are checked.

Through, homologous structures where structures are similar in organisms that share the same ancestor. Example, wings of bat and wings of bird.

Through, analogous structures where structures are similar in function in different organisms. Example, fore limbs of man and monkey which are used for grabbing.

2. COMPARATIVE EMBRYOLOGY;

This is done to check embryo development in different organisms throughout time and check the similarities and differences in their development. Example, embryo of man and fish both have gills at embryo stage and in fish they develop but in man they disappear before birth.

3. FOSSILS RECORDS;

The study of fossils shows the evidence of evolution as scientists study the fossils and the development of organisms present, it displays the changes that have occured throughout the years and how other organisms share ancestors and have evolved.

4. MOLECULAR BIOLOGY;

The study of the genes of organisms to check the relationship between organisms and the changes they have undergone through time. Molecular similarities show shared ancestry of organisms. Example, human and chimpanzee share a common ancestor because they both have a gene that encodes insulin hormone.

Explanation:

Water molecules moving across the plasma membrane until solute concentrations are equal on both sides of the membrane best describes the process of osmosis in an animal cell .

Osmosis is the process in which molecules move  from a region of higher concentration to that of a lower concentration across a semi-permeable membrane.

Osmosis provides a balance between the elements in which organisms are exposed to. A very high concentration may cause cells to shrink and die hence the reason to maintain a balance for optimal functions and survival.

What is osmosis? Why are they assuming the large molecules will stay on their own side of the membrane? The membrane is semipermeable, so the membrane only allows some molecules through and not others. In this case, it doesn't allow the large molecules through.

Explanation:

Hope It Helps

It is assumed that the large molecules will stay on their own side of the cell membrane because the membrane is semipermeable which only allows the passage of some molecules in and out of the membrane.

A cell membrane may be defined as a type of biological membrane that significantly separates and protects the inner environment of all cells from the outside environment. It is semi-permeable in nature.

The cell membrane consists of a lipid bilayer that is semi-permeable. The cell membrane regulates the transport of materials entering and exiting the cell.

The ability of a molecule to travel across a membrane depends on its concentration, charge, and size. In general, molecules diffuse across membranes from areas of high concentration to low concentration. Cell membranes prevent charged molecules from entering the cell unless the cell maintains an electrical potential.

Answer:

It becomes more common

Explanation:

Even if the trait is recessive if it is beneficial to a population then it will become more common because those with the trait are more likely to survive. For example, if a population of beetles lives on green grass and the dominant trait is for the beetles to be black and the recessive trait is green then the green ones will survive because the black beetles will be eaten first.

Photosynthesis requires energy to build organic molecules.

Remove brackets before and after requires and comma in the sentence, it will be correctly punctuated as above.

Answer:

Explanation:

photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.
