Explanation:

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.

Answers

(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.

Explanation:

The food we eat contains various nutrients mainly, carbohydrates, protein, and fat. The carbohydrate that is we eat has glucose as the primary product and also the substrate in the process known as cellular respiration.

Cellular respiration is a process in which glucose molecules are broken down in order to provide energy in the form of ATP with the help of oxygen. It is called aerobic respiration as it required oxygen for the complete oxidation of the substrate.

D 5' TCCAGTCCA 3

Answers

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'

The statement that explains the importance of carbon in our cells is that carbon affects the function of the cell. So the correct option is A.

What is the importance of carbon?

The most common chemical element present on our Earth is carbon. It has the symbol C and an atomic number of 6. The carbon atom is a member of the fourteenth group present on the periodic table.

The word carbon is derived from the Latin word 'carbo', which means coal. Carbon is also the 15th most abundant element that is present in the crust of the Earth. On the earth, carbon is the fourth most abundant element ranked after hydrogen, helium, and oxygen.

Carbon atoms, when bonded together in different ways,  are called as allotropes of carbon. Diamond, graphite, and amorphous carbon are the three allotropes of carbon.

They have different properties. Graphite is one of the softest known substances while diamond is the hardest known substance.

Therefore the correct option is A.

amaging a world without plants. will it be different world. think and write two lines on this​

Answers

It will definitely be a different world because they support natural and human food systems and provide homes for countless species including us, through building materials. Yet we often treat trees as disposable: as something to be harvested for economic gain or as an inconvenience in the way of human development. Since our species began practicing agriculture around 12,000 years ago, we’ve cleared nearly half of the world’s estimated 5.8 trillion trees.

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

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.

Answers

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

Answers

Answer:

Stomata

Explanation:

Photosynthesis is a unique phenomenon in certain organisms like plants. It is the process whereby they produce their food, in form of an organic compound called GLUCOSE. To synthesize this sugar, plants need a carbon source.

Plants utilize carbon dioxide (CO2), which is an inorganic carbon compound as CARBON SOURCE to synthesize glucose molecule in the process of photosynthesis. This carbon dioxide (carbon) is taken in by the plants via their STOMATA, which is a pore or opening present on their leaves.

The STOMATA opens and closes in order for gaseous exchange to occur i.e. take in CO2 (carbon dioxide), expel O2 (oxygen).

Document 1- Excerpt from Indians are Us, by Ward Churchill (1994)In 1493 Columbus returned with an invasion force of seventeen ships, and was appointed by the Spanish Crown as governor of the Caribbean islands and the mainland of America, a position he held until 1500. Setting up shop on the large island he called Espanola (today Haiti and the Dominican Republic), he quickly developed policies of slavery (encomienda) and organized slaughter against the native Taino population. Columbuss programs reduced Taino numbers from as many as eight million at the beginning of his rule to about three million in 1496. Perhaps 100,000 were left by the time of his departure. His policies remained and by 1514 the Spanish census (population count) of the island showed barely 22,000 Indians remaining alive. In 1542, only two hundred were recorded. Thereafter, they were considered extinct, as were Indians throughout the Caribbean Basin, a total population which totaled more than fifteen million at the point of first contact with Columbus was now gone.Document 2- Excerpt from Columbus, Hero or Villain by Michael Pucci (1997)Contrary to what some say, Columbus was a courageous man. He challenged popular opinion when nobody else believed him. He did what no other explorer dared to do. He was determined to find the route to Asia when everybody else was afraid to. American Indian activists criticize Columbus for bringing disease to America and act as if that was his entire goal when setting sail from Europe. It is ridiculous to claim that he knowingly brought over these sicknesses and purposely infected people with it. Columbus is also slammed for owning slaves. What leader in 1492 did not own slaves? The fact that Columbus did own them is irrelevant to any issue. Columbus did not cause environmental destruction either. He paved the path for the settlement of America.
