Answer:

Changes from flooded to drained conditions in soils stimulate changes from aquatic to terrestrial vegetation and decrease the algal contribution to total primary production.

Which of the following helps a species adapt to a changing
environment?
A Having fewer offspring
B Having more offspring
C Decreasing genetic variation
D Increasing genetic variation

Answers

Answer:

D

Explanation:

I think it is D because if you increase your genetic variation then you will have more population of, well "yourself" - therefore making more chances to survive. although don't take what I say word-for-word because I'm just a noob at this stuff. if it pops up wrong, please notify me why it is wrong so that I can improve.

By increasing genetic variation will help a species adapt to a changing environment. Therefore, the correct option is D.

What is genetic variation?

Genetic variation refers to the diversity of genetic information within a population or a species. It is the result of differences in the DNA sequences of individuals, which can arise through a variety of mechanisms such as mutations, genetic recombination, and gene flow.

It provides the raw material for natural selection to act upon. In a changing environment, individuals with certain traits may have a higher chance of survival and reproduction, and their traits may become more prevalent in the population over time.

Therefore, increasing genetic variation through mechanisms such as mutation, genetic recombination, and gene flow is critical for a species to adapt and survive in changing environments. Hence,  the correct option is D.

Recall that the normal range for the hematocrit for a female is 37 - 47%, and the normal range for the hemoglobin level for a female is 12 - 16 g/100 ml. Describe hemoglobin and hematocrit values for the female with iron-deficiency anemia. Recall that the normal range for the hematocrit for a female is 37 - 47%, and the normal range for the hemoglobin level for a female is 12 - 16 g/100 ml. Describe hemoglobin and hematocrit values for the female with iron-deficiency anemia. They were both below normal. The hemoglobin was normal, and the hematocrit was below normal. They were both normal. The hemoglobin was below normal, and the hematocrit was normal.

Answers

Answer:

The hemoglobin was below normal, and the hematocrit was normal.

Explanation:

Hemoglobin is an essential protein in the bloodstream, as it is primarily responsible for the transport of oxygen throughout the body. It is also responsible for the red coloration of the blood, as it is present in the red blood cells. The hematocrit, in turn, is a laboratory parameter to determine the amount of red blood cells in the blood and also to determine the total blood volume.

Although the results presented by the hematocrit are important in determining whether a person has anemia, women with normal hematocrit values may be anemic, primarily because the hematocrit results may be associated with the amount of water in the blood. What is essential to determine if a woman is, in fact, with anemia, due to iron deficiency, is the hemoglobin values that are below normal.

Which mutation scenario will always lead to natural selection?(1 point) A. a mutation causes a specific advantage within the population B. a mutation causes an inactivated gene to be reactivated C. a mutation causes a specific variation within the population D. a mutation causes a gene to become inactivated

Answers

A mutation scenario that will lead to natural selection is one that causes a specific variation within the population. Thus, the correct option for this question is C.

What is Mutation?

A mutation may be defined as a type of process that significantly involves sudden, stable, and inheritable changes in the genetic material of an organism. The organism that undergoes mutation is called a mutant. The agent of mutation is called mutagen.

According to the context of this question, the process of mutation never causes a positive influence on the organisms, but with respect to time organisms become adapted or habitual.

A Mutation may be random and spontaneous so, it does not always involve an inactivated gene being reactivated. It sometimes involves the introduction of a new gene that facilitates specific functions.

Therefore, a mutation causes a specific variation within the population is a mutation scenario that will lead to natural selection. Thus, the correct option for this question is C.

Answers

Answer:

Yes.

Explanation:

The creation of one type of kidney cell will be sufficient in forming a functioning kidney because one type of cells allow the kidney to perform its one function i.e. filtering of blood. Epithelial stem cells are the cells that is responsible for the function of a kidney. The kidneys have only epithelial stem cells which performs only one function which removing water material, excess salts and water from the body. so we can say that one type of kidney cell is sufficient for the functioning of kidney.

Due to all the hard work you put into your literature review and planning your procedures, the steps that you need to take to conduct your experiment successfully have already been set. While you conduct your experiment, you will need to keep a daily journal where you record the activities you undertake that are relevant to the experiment and also where you record any data that you collect. This is your experiment log and serves as a record of your work while also allowing you to make a record of any changes or modifications you may need to make during the experiment.Conducting the Experiment and Keeping an Experiment JournalFollowing the procedure that you established in the previous part of this project, set up your experiment and begin running it. Every day while your experiment is running you will make an entry in your journal. Record what activities you completed (refer to your outlined procedure to make sure you are following the procedure that you established), any modifications that had to be made to your set up or procedure, and any observations or data you collect. Even on days when you do not collect data (depending on your experiment, there may not be data collection every day), make an entry in your journal. Each journal entry should be clearly labeled with the date on which it was entered. You do not need to type up all your entries, but make sure that your journal entries are neatly written, as they will be evaluated by your instructor.Depending on the topic and design of your experiment, the period of time during which you conduct and record your experiment may range from one to several weeks. In consultation with your instructor, you will establish a timeline for the evaluation of your journal. If you are running a shorter experiment, your journal may be evaluated several times over the course of one or two weeks. If your experiment takes longer to complete, you may have a weekly review over the course of a month. Follow the guidelines provided by your instructor.Collecting DataAll experiments generate data. This data allows the scientist to evaluate the success of the experiment and make interpretations about the results generated by the investigation. When you record your data, you must collect it as consistently as possible. Returning to the plant experiment, it would be best to measure the plants on a set schedule. For example, you might choose to measure the plants every Thursday at 3 pm. It is important to measure the plants at the same time each week so that the difference in growth you might observe is a reflection of the experimental condition, not simply longer growing time. Additionally, it is important to use the same instruments to collect data. The plants should be measured with the same ruler or measuring tape each time. This helps reduce any error or bias that might be introduced by using different instruments to make measurements. Whatever measurements or data you collect, do so in a consistent manner. Use the same instruments, the same scales, and record the data in a standardized manner. It is also a good idea to record your experiment using photographs. This will help you later during analysis and provides information for others who might be interested in recreating your experiment. Record your data in your experiment journal, where it will be reviewed by your teacher on an on-going basis. Submit your journal to your instructor according to the schedule you have established together.
