Explanation:

This makes no sense to me...

Diatoms have two distinct shapes: a few (centric diatoms) are radially symmetric, while most (pennate diatoms) are broadly bilaterally symmetric.

Any member of the vast group of several genera of microalgae that can be found in the world's oceans, streams, and soils is referred to as a diatom.

Diatoms can photosynthesize, which allows them to change the dissolved carbon dioxide in the water into oxygen.

For higher-ranking organisms in the food chain, like invertebrates and tiny fish, they serve as a major source of food. In the energy and nutrition cycles of water resources, diatoms can also be vital players.

Diatoms can be divided into two shapes: pennate diatoms, which make up the majority, are broadly bilaterally symmetric, and central diatoms, which make up the minority.

Thus, these are the characteristics of diatoms.

Answer:

The length of daylight and nighttime would decrease.

Explanation:

If 24 hours was decreased to 20, it would shorten night and day time.

Answer: 20. A 21. B 22. A=2, B=3 23. A=4, B=3 25. B

Explanation: A has H2O (water). B has a hydrogen ion, so acidic.

In B H2CO3 is carbonic acid

The loss of hydrogen atoms leads to the formation of acids and the hydroxide forms bases. Equation A represents the formation of water, and equation B shows the acidic solution.

Chemical reactions are said to be involved in producing products from the reactants that undergo chemical changes. Water is formed by reacting the four hydrogens and one oxygen molecule as:

2H₂ + O₂ → 2H₂O

H₂CO₃ → H⁺ + HCO₃

Here, carbonic acid dissociates a proton that makes the solution acidic.

Therefore, the first equation represents the formation of water by oxygen and hydrogen atoms.

Explanation:

The thyroid hormones are produced by the thyroid glands and they're the triiodothyronine and the thyroxine. The thyroid hormones are required in metabolism regulation, performs digestive functions, controls the muscle of the heart, and develops the brain.

If thyroid hormones are not released, you can regulate body temperature by shivering and which requires a greater use of oxygen.

Answer:

A

Explanation:

The correct answer would be that Watson and Crick's structure of DNA was not done until 1953.

The fact that chromosomes are condensed together in the nucleus, are not distinguishable during interphase, and a method had not yet been devised to halt mitosis at metaphase could have plausibly delayed the successful counting of human chromosomes.

On the other hand, the discovery of the structure of the DNA could not have delayed the study of chromosomes because the DNA structure has no bearing on the karyotyping of chromosomes.

The chromosomes of organisms are best studied using a relevant microscope during metaphase when they would have fully decondensed and align at the equator of the cell or the metaphase plate. At the interphase phase of the cell cycle, chromosomes are full condensed under the view of the microscope.

The correct option is, therefore, A.

The given question is incomplete as it lack the options, however, answer can be given by the provided information.

Answer:

The correct answer is - 3:1 ratio.

Explanation:

In the question it is given that both male and female both are heterozygous for the trait, let assume dominant allele A and recessive allele a so the the gene for the both male and female is Aa.

Punnett square for the cross between both:

gametes: A, a and A, a.

A a

A AA Aa

a Aa aa

here two out of four are heterozygous dominant and one is dominant and one is recessive.

thus, 3 out of 4 are dominant and one out 4 are recessive.

thus, the answer is 3:1 ratio

Answer: 1. The nitrogen cycle is a biogeochemical cycle.

2. The carbon cycle is a biogeochemical cycle.

Explanation:

1. The nitrogen cycle can be defined as the biogeochemical cycle in which the atmospheric nitrogen is utilized by the plants which is fixed by the soil bacteria. The nitrogen becomes the part of the biosphere as plants utilize it as an important development mineral. The nitrogen cycle involves the nitrogen fixation in which plants fix nitrogen by the help of bacteria into ammonia, nitrification in which the ammonia is converted into nitrite, nitrogen assimilation in which the plants assimilate and utilize the nitrogen for their growth and development, and denitrification involves the reduction of nitrite into atmospheric nitrogen. The conversion of nitrogen is carried out via physical and biological processes.

2. The carbon cycle involves the atmospheric carbon dioxide being circulated in plants as they utilize it for photosynthesis. The carbon dioxide is fixed by the plants in the form of carbohydrate which is consumed by the animals and on decomposition of plants and animals dead matter release carbon dioxide gas to the atmosphere. This allows the recycling of the carbon dioxide gas in the environment.
