Describe the thickness of the uterus lining during
menstruation process.
Answer:
As the cycle progresses and moves towards ovulation, the endometrium grows thicker, up to about 11 mm. About 14 days into a person's cycle, hormones trigger the release of an egg. During this secretory phase, endometrial thickness is at its greatest and can reach 16 mm.
Explanation:
Answer:
During this timeframe, the uterus is in the proliferative phase. Estrogen induces growth of the functional layer of the endometrial lining, which enables it to grow from about 1-3 mm post cycle to 6-8 mm approximately. Days 12-16 of the menstrual cycle At this point, the endometrial layer is about 6-8 mm thick.

If two individuals were heterozygous for freckles, which are a dominant autosomal trait, what percentage of their offspring would you expect to have freckles
Answer:
75%
Explanation:
Firstly, an autosomal dominant trait is a trait the becomes expressed in the presence of only one affected allele, which is the dominant allele. Freckles is said to be an autosomal dominant trait meaning that the presence of the dominant allele (F) makes a person have the condition.
According to this question, If two individuals that are heterozygous for freckles cross i.e. Ff × Ff, the following proportion of offsprings will be produced: FF, Ff, Ff and ff (see punnet square).
From the genotypic observation of the produced offsprings:
FF, Ff - possess freckles
ff - do not possess freckles
Since, 3 (FF, Ff and Ff) of 4 offsprings possess freckles, the percentage of offsprings expected to have the condition will be:
3/4 × 100 = 75%
The pharynx is the structure in the body that serves as a pathway of both air and food. How does the body make sure that food does not get into the lungs?
Answer: The body makes sure that food does not get into the lungs because the epiglottis closes the air pathway so that food will not enter it.
Answer:
food getting to the lungs will be aspiration
Explanation:
A flap of tissue called the epiglottis sits over the top of the trachea. This flap blocks food and drink from going down into the trachea when you swallow hence preventing food from getting into the lungs

In what order does blood flow through the body and heart? A. Right atrium, left atrium, lungs, right ventricle, left ventricle, body. B. Right atrium, left ventricle, lungs, left atrium, right ventricle, body. C. Right atrium, right ventricle, lungs, left ventricle, left atrium, body. D. Right atrium, right ventricle, lungs, left atrium, left ventricle, body.
Answer:
answer is D
l
Explanation:
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.
The statement that describes the order blood flows through the body and the heart is:
Right atrium, right ventricle, lungs, left atrium, left ventricle, body.What is blood?It is a red liquid with different shades that varies according to the amount of oxygen it has inside, that is, hemoglobin.
Characteristics of blood circulationIt is a necessary substance for oxygenation to occur between cells, as well as to regulate blood pressure.Each side of the heart is divided into an upper chamber called the atrium and a larger, lower chamber called the ventricle.The blood flows since it has left the right ventricle, has been oxygenated by the lungs and has returned to the left atrium through the pulmonary veins, it is carried to the left ventricle.Therefore, we can conclude that the main function of the blood is to ensure that oxygen and nutrients are distributed between the cells of each organism.

What are the methods of waste disposal ? Write in briefly.
Answer:
Methods of waste disposal are :-
Biogas plant: - Biodegradable material is used to produce biogas and manure.
Sewage treatment plant: The drain water is treated at plants before adding it to river.
Land filings: - The waste are buried in low-lying areas and compacted with bulldozers.
Composting: - Organic waste are filled in compost pit to make compost for plants.
Recycle: - This means that you collect plastic, paper, glass and metal items and recycle these materials to make required things instead of synthesizing or extracting fresh plastic, paper, glass or metal. In order to recycle, we first need to segregate our wastes so that the material that can be recycled is not dumped along with other wastes.
Reuse: - This is actually even better than recycling because the process of recycling uses some energy. In the ‘reuse’ strategy, you simply use things again and again. Instead of throwing away used envelopes, you can reverse it and use it again. The plastic bottles in which you buy various food-items like jam or pickle can be used for storing things in the kitchen.
Refuse: -This means to say No to things people offer you that you do not need. Refuse to buy products that can harm you and the environment, say No to single-use plastic carry bags.
Repurpose - This means when a product can no more be used for the original purpose, think carefully and use it for some other useful purpose. For example, cracked crockery, or cups with broken handles can be used to grow small plants and as feeding vessels for birds.

Is the cell an open or closed system? Explain your
answer using at least one example of a cell
organelle and its function
· In an open system matter and energy can be transferred
· In a closed system only energy can be exchanged
· In an isolated system neither matter nor energy can be exchanged
· The cell has to be an open system because it needs to exchange matter and energy and the only way to do so is through an open system
· As an open system the cell allows nutrients to enter the cell and waste products to exit the cell
· The cell does this through the use of a semi-permeable membrane
· It needs nutrients in the forms of glucose, ions and many other molecules.
· The nutrients can come into the cell through either passive or active transport
· In passive transport the nutrients naturally move from a higher concentration gradient to a concentration gradient.
· During active transport the particle need to move against the concentration gradient. To do this the cell needs energy to transport the materials. The energy comes in the form of ATP.

Hantavirus is a relatively rare emerging infectious disease that is spread by contact with the contaminated feces and urine of rodents, such as deer mice. It does not spread between people and causes flu-like symptoms. How would scientists most likely recommend that the disease be controlled?
Answer:
They would instead focus on controlling and diminishing the rodent population.
Explanation:
They would instead focus on controlling and diminishing the rodent population. The best solutions are always those that target the cause of the problem. Therefore, since the cause of the virus are rodents and that is how the virus spreads, then targetting the rodent population would be the best choice. The scientists would have to figure out a way of keeping track and controlling where the rodent population moves, as well as figuring out how to control their reproduction and diminish their population size. All of this while also trying to predict the possible effects that the population size can have on the environment.
