Stickleback fish protect themselves from predators with a thick covering of brownish plates. They feed on
small aquatic organisms and are preyed upon by bigger fish like trout. In a certain lake, the number of
stickleback fish was documented over a period of 30 years. During this time, the clarity of the lake water
also changed.

The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old.

Explanation:

Answer:

1)Protein is composed of amino acid.

We can identify protein by sequencing amino acids in peptide.

Carbohydrates is primarily avilabke energy source.

2) Proteins and nucleic acids are made up of C H O But carbohydrates and lipids consist of C H O N.

3)Nucleic acid DNA and RNA store and transmit genetic information from one generation to next generation.

Nucleic acid as present in body therefore not considered as essential nutrients.So dietary sources are plant and animal foods like meat fish vegetables etc.

The optimal ranges for the formation of oxygen bubbles vary between each plant, however, only water, c02, and temperature are limiting factors for photosynthesis.

This question is based on observations made during the course of an experiment designed to measure the optimal ranges at which oxygen bubbles form, given that these are an indication of photosynthesis.

Due to this, the information given will be generalized. Firstly, there is no exact optimal range of light for the formation of oxygen bubbles (photosynthesis) given that this is not a limiting factor.

Excess of light will have no effect on photosynthesis, only the lack of light can cause negative effects, therefore any light past the minimum threshold is fine.

On the other hand, water, light, and C02 are in fact limiting factors and have optimal ranges. For water, this optimal range varies greatly and therefore I cannot offer a general value, but an excess of water will "drown" plants by not allowing the formation of air pockets in the soil.

C02 sits at an optimal range of 1,000-1,300ppm for the best results. Lower concentrations cause a lower rate of photosynthesis given that it is the primary substrate for the process to begin. At too high levels, plants will have to adapt which can slow the process.

Finally, temperature is also a limiting factor for photosynthesis. Its exact value cannot be given since it varies greatly between plant species.

However, in general, terms, since it is an enzyme-dependent reaction, we can apply the general temperature at which enzymes function best which is around 37 degrees.

Foods or beverages created through managed microbial growth and enzymatic conversion of food components are referred to as fermented foods.

Biotechnology is the application of biology to the problem-solving and product-making processes. The most well-known application of biotechnology is the use of genetic engineering to produce therapeutic proteins and other medications.

Because the production of antimicrobial metabolites (such as organic acids, ethanol, and bacteriocins) lowers the danger of contamination with pathogenic bacteria, food fermentation has historically been used as a preservation technique.

Therefore, Foods or beverages created through managed microbial growth and enzymatic conversion of food components are referred to as fermented foods.

The outcome differs in the way that the protein folds itself at each level. The changes in the way that it folds lead to:

modifications in the function, shape or in the combination with other proteins.

Protein has different levels of structure. Each of them is related to how the amino acids and other molecules interact with each other. Hair is made of proteins, so if one of the structures is affected, the hair is too.

Let's analyse what happens in each level of structure:

In conclusion, the modification of the secondary structure changes the interaction between the elements of the protein giving hair with different shapes.

The shelf fungus and slug in the forest community do not compete with each other as they have the same habitat, but different niches. Thus, option A is correct.

Habitat is defined as the place where the species resides while the niche is the role of the specific organisms or the species in that particular habitat or environment. The niche includes the impact of the species on the habitat.

The shelf fungus and the slug both live on the side of the tree and hence have the same habitat but the fungus takes minerals from the tree and the slug from the algae making them differ in the niche.

Therefore, the fungus and slug have the same habitat but different niches.

Explanation:

Meiosis occurs in two phases. Meiosis I is the reductive phase, while meiosis II is non-reductive. The point at which the cells first become haploid is at the end of meiosis I, after homologous chromosomes separate.

-----------------------------------------------------

Through Meiosis, a diploid cell (2n) produces four haploid daughter cells (n).  

After DNA replication there are two meiotic phases.  

1. In the first phase, Meiosis I:  

Cytokinesis occurs

2. In the second phase, Meiosis II:  

Cytokinesis occurs.  

To answer this question, focus your attention on Meiosis I. During the anaphase homologous chromosomes separate. After this point, the nuclear membrane forms in the telophase, followed by cytokinesis. The result is two haploid cells.

Answer:

A movement of a body part away from the midline, either of the body as a whole or that of the hand or foot, is termed abduction (L., to carry away). A movement of the body part back toward the midline (i.e., to the anatomical position) is known as adduction.

Explanation:

Mark me brainly please.

Abduction is a movement away from the body's midline. Abduction is the term for a bodily part's lateral movement away from the body's midline.

Thus, body parts are divided or spread apart in this process. Abduction of the arms, for instance, occurs when you raise your arms from a resting posture and spread them out to the sides. Similar to this, you are practicing leg abduction when you stretch your legs apart.

Adduction, or the movement in the direction of the midline, is the reverse of this action. Important terminology like abduction and adduction are used to describe movement in respect to the body's midline in anatomical and physiological descriptions.

Answer:

Solar energy is converted to chemical energy in the photosynthesis process, which converts water and carbon dioxide to glucose.

Explanation:

Hope this helps!

During photosynthesis, the energy for converting carbon dioxide into sugar comes from the sun, it is solar energy.

Photosynthesis, the method used by plants and other autotrophic organisms to make food, converts carbon dioxide into glucose and oxygen, both of which are vital for life.

Photosynthesis in plants uses the green pigment chlorophyll and produces oxygen as a byproduct. Plants use their leaves to trap light energy during photosynthesis.

Plants use the sun's energy to convert water and carbon dioxide into glucose, a sugar. Plants use glucose for energy and to generate other compounds such as cellulose and starch.

Therefore, the energy used to convert carbon dioxide into sugar comes from the sun during photosynthesis; this is known as solar energy.
