Large areas on the leaves of some plants lack chlorophyll and are therefore not green in color. How does this most likely affect photosynthesis? Not enough sunlight is captured in these areas of the leaves. Carbon dioxide cannot enter these areas of the leaves. Too much glucose builds up in these areas of the leaves. Oxygen cannot be released in these areas of the leaves.
(Not enough sunlight is captured in these areas of the leaves)
The plants are of green color due to the pigment chlorophyll. the chlorophyll plays a crucial role in photosynthesis, the process of preparing food.
The correct answer is:
Option A. Not enough sunlight is captured in these areas of the leaves.
The functioning of chlorophyll can be explained as:
Chlorophyll is the green color pigment present in the chloroplast of the leaves. The pigment is involved in the capturing of sunlight and imparting green colors to the plants. The plants lacking chlorophyll will not be able to perform photosynthesis. The process of preparing food in the presence of sunlight, chlorophyll, and carbon dioxide. The products of photosynthesis are oxygen and sugar molecules.
Thus, the correct answer is Option A.

there are six classes of nutrients that must be considered when planning your diet: water, proteins, carbohydrates, fats, vitamins, and minerals. most foods or ingredients include more than one of the six basic nutrients. for example, although most people usually think of corn as containing carbohydrates, it is important to remember that a kernel of corn contains all six basic nutrients.
Match the words to the appropriate blanks in the sentences.
_______nutrients 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 _________ which you consume in small quantities
_________ can develop very quickly when exercising in hot/humid weather conditions.
_________are also called 'body builders" due to their function within the body________ are the building blocks of proteins.
1. glucose and fructose
2. essential
3. incomplete
4. proteins
5. fat soluble
6. plant
7. amino acids
8.saturated fats
9. micronutrients
10. dehydration
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.

Life could not exist on Earth without trees because they produce most of the oxygen that humans and wildlife breathe. Trees absorb carbon dioxide from the atmosphere and release oxygen using the process of photosynthesis. There would also be no rain without trees since trees absorb water from the soil and release it through evapotranspiration. Water vapor released through evapotranspiration is the major mechanism by which air is remoistened. Forests act as giant air filters for the world. Trees purify the air by absorbing pollutants such as sulfur dioxide and nitrogen dioxide, reducing pollution. Trees also help prevent topsoil erosion because they break the force of wind and rain on soil, their roots bind the soil, and their decayed, falling leaves are absorbed by the earth and enrich the soil. Trees conserve rainwater and reduce water runoff and sediment deposit after storms.Additionally, trees provide a supply of lumber, seeds, and fruit. Further, dead trees that fall and get

Explanation:
A new fossil called Darwinius was discovered in Germany. It lived around 47 mya. It had a small brain, short snout, and postorbital bar. Its diet probably included a lot of fruit and leaves. It did not have a dental comb. It had nails instead of claws and was probably an arboreal quadruped. Researchers disagree about whether the fossil is more similar to living haplorhines (the group that includes tarsiers, Old and New World monkeys, apes, hominins) or more similar to strepsirrhines (lemurs, lorises)
Required:
a. Describe two features that the fossil shares in common with living haplorhines.
b. Describe two features that the fossil shares in common with living strepsirrhines.
Explanations:
Darwinius is also known as Ida. some scientists have grouped it to be a member of the adapiforms. it's remains were unearthed in Germany. it is regarded as a female because it's skeleton lacks baculum.
Instead of claws darwinius have nails. they could be classified as transitional fossils due to its links with living strepsirrhines and also living haplorhines
similarities with haplorhines:
1. they share similar body structure and tail, also their nails are similar
2. there feeding is almost the same in terms of diet they are carnivores.
similarities with strepsirrhines:
1. they are both mammals
2. they have close body structure and also almost same tail

C 5'TGGACTGGA 3
D 5' TCCAGTCCA 3
The correct complementary DNA sequence of 3'AGGTCAGGT 5 is - D. 5' TCCAGTCCA 3'
DNA is made of two strands of DNA strands coiled together and form a ladder-like shape. DNA molecules have four nucleotide bases that joined both strands together that are Adenine (A), Guanine (G), Thymine (T), and Cytosine(C).
Each nitrogenous base has its own complementary base in a double-helical structure.The A is complimentary T and G will have CThe complementary strand is always present in an antiparallel directionIf one strand is 3' to 5' then the complementary strand would be 5' to 3'So, in the given sequence: 3'AGGTCAGGT 5
