What is photosynthesis???​

Answers

By definition, photosynthesis is a metabolic process carried out by certain cells of autotrophic organisms, that is, those that have the capacity to make their own food, such as plants.

With this process, plants capture the energy of sunlight and transform it into chemical energy, to produce organic matter.

Photosynthesis takes place in 2 stages:

In the first stage the plants absorb water from the soil through the roots. Through their stems they transport it to their leaves. In these it meets the sunlight captured by chlorophyll, which breaks the water molecule, separating hydrogen (H) from oxygen (O₂). The other stage is capturing carbon dioxide. This provides the carbon and oxygen atoms that, together with hydrogen and stored energy, will form the glucose molecule, from which compounds are produced that are the basis of food for plants and other living beings.

Then, sunlight, carbon dioxide and water are needed for the photosyntesis, while oxygen is released to the environment.

which of the following hormones produced in the anterior pituitary stimulates the production of progesterone and estrogen by ovaries and is needed for ovulation?

Answers

Luteinising hormone stimulates the corpus luteum to produce progesterone, which is required to support the early stages of pregnancy, if fertilisation occurs.

Luteinizing hormone stimulates the corpus luteum to produce progesterone, which is required to support the early stages of pregnancy, if fertilization occurs.

what are the role of Luteinizing hormone ?

These hormone are released from ductless Endocrine cells which release their secretion i.e., hormones directly into blood.

The  FSH (follicle stimulating hormone) is secreted by pituitary gland  which helps in controlling menstrual cycle and stimulation of ovaries for egg production.

The hormone LH (Luteinizing hormone) is secreted from pituitary gland,  helps in physical development and maintaining pregnancy.

Thus, both FSH and LH are produces by pituitary gland and their functions are to control menstrual cycle and maintaining pregnancy respectively.

Conclusion:
Be sure to answer the following reflection questions as a summary in the conclusion of your lab report:
Was your hypothesis correct? Why or why not? Be sure to include evidence from the data you collected to support your conclusion.
Based on your data, what can you infer about the length of time spent in each stage of the cell cycle?
What stages were the longest and shortest? Give a brief explanation of why these stages may have that time period.

The distinguishing visible features of each stage of the cell cycle include chromosome condensation, mitotic spindle, equatorial plate and formation of two cells.

What is the cell cycle?

The cell cycle is a series of well-defined steps in the life of a cell that begins with cell growth and end with its division.

The cell division has a series of steps that may be classified according to the phenomena that occur in these phases.

For example, chromosomes condense during the first stage of cell division (prophase), where they migrate to the equatorial plate at metaphase.

In conclusion, the distinguishing visible features of each stage of the cell cycle include chromosome condensation, mitotic spindle, equatorial plate and formation of two cells.

O There are bubbles like carbonation on the ocean surface.
O Fish we catch and eat from the ocean are made of carbon.

Answers

The concentration of carbon is increased in the oceans have made them more acidic.

Increased carbon concentration in the oceans which have made the ocean water more acidic is the indication that more carbon is absorbed by the ocean. When carbon absorbed by the ocean, the carbon reacts with water which produced carbonic acid.

This carbonic acid decrease the pH of the ocean water that adversely affect the marine organisms especially coral reefs. When the pH of the ocean water increases, bleaching of coral reef occurs because the algae living on them die so we can conclude that the concentration of carbon is increased in the oceans have made them more acidic.

A. H+ ions will stop moving through the protein.
B. H+ ions will move in the other direction through the protein.
C. H+ ions will continue to move through the protein in the original direction but at a slower rate.
D. H+ ions will begin to move through the phospholipid portion of the membrane in the original direction.

Answers

H+ ions will stop moving through the protein is the effect of not having ATP

available to supply energy to this process.

ATP is the form of energy used by cells and it ensures that cells perform their

daily activities optimally. ATP is needed in a lot of metabolic reactions and

transportation of materials within cells.

When there is a lack of ATP, it means there is no energy required to

transport or move substances within a cell. This means that the H+ ions will

stop moving through the protein and is the most appropriate choice.
