Black rats are generally omnivorous. They are harmful to farmers because they eat various types of crops. So, for removing Black rat from the crop fields, farmers follow different types of protective ways.

The table below summarizes Mendel’s results for the F2 generation. Mendel’s Results Plant height 787 tall 277 short Flower color

Gnom [1K]

Answer:

2001

Explanation:

This question showcases a table that displays Mendel's results (figures) when he crossed pea plants and observed different characters in the plant. Mendel worked with different phenotypic characteristics in the pea plant.

According to the table, the result were for seven characteristics including height, flower color, flower position, pod color, pod shape, seed color, seed shape. Based on the observation of the number of F2 offsprings that possessed dominant trait and recessive trait for each character, we will notice that it follows an approximate phenotypic ratio of 3:1

1. Plant height 787 tall 277 short (3:1)

2. Flower color 705 purple 224 white (3:1)

3. Flower position 651 middle of stem 207 end of stem (3:1)

4. Pod color 428 green 152 yellow (3:1)

5. Pod shape 882 inflated 299 constricted (3:1)

6. Seed color 6,022 yellow X green

7. Seed shape 5,474 smooth 1,850 wrinkled (3:1)

This 3 dominant : 1 recessive ratio is the ratio got in the F2 offsprings when he observed the seven characteristics in pea plants. Hence, the seed color will also follow the same 3:1 ratio

Therefore, 2001 is the result Mendel obtained in the F2 offsprings for the recessive trait of seed color characteristics in his experiment, which actually depicts the 3:1 ratio. Hence, X (green seed color) is 2001

There are six classes of nutrients that must be considered when planning your diet: water, proteins, carbohydrates, fats, vitami

KiRa [710]

Answer:

Essential nutrients cannot be synthesized by the human body but are required for optimal functioning. Therefore. They must be obtained from food. Omega-3 fatty acids are prime examples.

You consume macronutrients (water. proteins, carbohydrates, and fats) in large quantities as opposed to micronutrients which you consume in small quantities

Dehydration can develop very quickly when exercising in hot/humid weather conditions.

Proteins are also called 'bodybuilders" due to their function within the body. Amino acids are the building blocks of proteins.

Explanation:

Essential nutrients are those nutrients that are required for the proper functioning of the body but cannot be synthesized by the body. They are obtained from external sources such as vegetables or synthesized artificially in the laboratories. Micronutrients as the name implies are taken in small amounts. Examples are the different types of vitamins.

Dehydration occurs when a person loses a good amount of water through sweating or urination. It can easily occur while exercising in hot weather conditions. Proteins repair the cells in our body and are, therefore, rightfully referred to as bodybuilders. Amino acids form proteins.

What are the end products of lactic acid fermentation and alcoholic fermentation?

3241004551 [841]

Lactic acid fermentation produces lactic acid, while alcoholic fermentation produces ethanol. Both fermentation pathways also oxidize NADH to NAD+ during the process.

How many chromosomes are found in the organism that results from the union of a human sperm cell and an egg cell?

Liono4ka [1.6K]

A human has a total of 46 chromosomes (23 from daddy and 23 from mommy). :)
A sperm cell has 23 chromosomes and an egg cell that has 23 chromosomes. 23 + 23 equals 46. Sometimes (due to mutations), a person
may have less chromosomes than they need. This may cause some problems like Turner syndrome(treatment can help aid the situation but, it can't be cured).
Hope this helps you :)
