Answer:
Oogenesis in the female is the process that produces fertile eggs, ready for fertilisation by the male sperm. Each egg has only one of each of the 23 human chromosomes - normal body cells have a pair of each, having 46 chromosomes in total.
To produce egg cells, the process of oogenesis takes place in the female ovary. Progenitor cells divide through a cell division process called meoisis, which is also known as a reduction division.
Instead of one cell splitting into two identical cells, four cells are produced which have half the normal number of chromosomes - they are described as being haploid.
The four cells are all genetically different because the process of meiosis involves cross overs of the chromosomes during division, so mixing up the genes inherited from the woman's mother and the woman's father. This variation produces fitter offspring as it widens the genetic variation that is possible.Explanation:

10. What are two examples of "typos" that happen when DNA is being copied?
Answer:
DNA “typos” cause variation
Explanation:
Any time DNA is copied, a mistake or change can occur in the letters of the DNA sequence, or gene. These changes result in variations or differences in DNA from person to person.
The "typos" that happen when DNA is being copied is mutations and variations.
What are mutations?A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.
Moreover, mutations result either from errors in DNA replication or from the damaging effects of mutagens, such as chemicals and radiation, which react with DNA and change the structures of individual nucleotides.
Therefore, mutations within the DNA are a fairly common event. Mutations are random changes that occur within the sequence of bases in DNA. They can be large scale, altering the structure of the chromosomes.

Why a cell spends the majority of its time in interphase.
A cell spends the majority of its time in interphase because during this period the cell grows and synthesizes materials required during and after its division. During interphase, the cell duplicates its genetic material.
The cell cycle can be divided into a long interphase and a short mitotic (M) phase.
The interphase can in turn be divided into three phases: Growth 1 (G1) phase, Synthesis (S) phase and Growth 2 (G2) phase.
During the S phase, the cell duplicates its genetic material, which is sharply controlled by different cellular mechanisms (e.g., checkpoint mechanisms).
During G1 and G2 phases, the cell synthesizes all the proteins required during the M phase and after cell division.

The image shows a facility that converts the energy of moving water into
electrical energy. What is one advantage of using this technology in place of a
coal-burning power plant?
A. It produces more water pollution.
B. It causes no harm to ecosystems.
C. It does not emit greenhouse gases.
D. It is fueled by a nonrenewable resource.
Answer:
C. It does not emit greenhouse gases.
The one advantage of using this technology in a coal-burning power plant is that it does not emit greenhouse gases. Therefore, option C is correct.
How does electrical energy formed from moving water?Electrical energy can be generated from moving water through a process called hydroelectric power generation. Hydroelectric power plants use the kinetic energy of moving water to spin turbines, which in turn generate electricity.
Hydroelectric power generation is a renewable source of energy that produces no carbon emissions or air pollution. It is one of the most widely used forms of renewable energy, providing electricity to millions of people worldwide.
However, the construction of dams and reservoirs can have significant environmental impacts on the surrounding ecosystems and habitats. Hence, option C is correct.

A scientist fills a glass container with water and places an aquatic plant inside the container, then closes the lid and places the
container in direct sunlight. The scientist observes small bubbles on the surfaces of the plant's leaves on days 1 and 2, but no
bubbles on day 3. The scientist concludes that the bubbles were caused by photosynthesis. Which substance should be
added to the water in order for the bubbles to reappear? (1 point)
Answer: Are there any options? you either add C02 because it has run out gas or you and in minerals that also contain C02.
Explanation: you need C02 to have photosynthesis, so with a closed off lid, the gas is going to eventually run out.
Carbon dioxide should be added to the water in the container in order for the bubbles to reappear in the glass container while placed in sunlight. Carbon dioxide is a component of photosynthesis.
What is Photosynthesis?Photosynthesis is the process by which plants prepare their own food in sunlight and in the presence of carbon dioxide gas. Photosynthesis process takes place in the chloroplast of cells.
Photosynthesis is an anabolic reaction in which carbon dioxide and water reacts in the presence of sunlight which is trapped by the chlorophyll present in the leaves of plant to produce glucose (carbohydrate) and oxygen gas, which is later utilized in the process of respiration.

Which process does the grass used to make the food this horse needs?
A.) Photosynthesis
B.) Respiration
C.) Eating
D.) Digestion
Answer:
Photosynthesis
Explanation:
Just like trees and other plants, grass converts energy from sunlight into sugar through the process of photosynthesis. This energy is used to convert water and carbon dioxide into glucose. Carbon dioxide is absorbed through the stomata in the leaf and water is mainly derived from uptake in the roots. Photosynthesis makes the grass green and healthy.
