What type(s) of variation do these characteristics show?
A Continuous variation only
B Discontinuous variation only
C с Both continuous and discontinuous variation
D
Neither continuous nor discontinuous variation
Answer:
The answer would be B. Discontinuous Variation Only.
Explanation:
Gender is discontinuous as there's only male and female. Sickle Cell/Normal is also discontinuous as you can only be one or the other. Same with blood group as there's only four types and no in-betweens.

What's is biosynthesis
Answer:
the part of an organism close to the flesh and the cells
Explanation:
Biosynthesis is a multi-step, enzyme-catalyzed process where substrates are converted into more complex products in living organisms. In biosynthesis, simple compounds are modified, converted into other compounds, or joined together to form micro molecules. This process often consists of metabolic pathways.
homeostasis is maintained through posterior pituitary endocrine hormones that act on the ______.

Which of the following is NOT a function of behavior?
A. To produce ATP.
B. To find food.
C. To reproduce.
D. To avoid predators.
Answer:
A to produce ATP as you are subconsciously producing ATP and you can not control it
Explanation:
To find food, to reproduce, and to avoid predators all are the functions of behavior except the production of ATP. Thus, the correct option is A.
What are the functions of behavior?Behavior is the range of actions and manners which are made by individuals, systems or artificial entities in a given environment. This can include other systems or organisms as well as inanimate physical environment.
The four main functions of behavior of an organism are attention, escape, access, and sensory needs. These four functions allow us to understand and categorize someone's actions, as well as determine the behavior of organisms such as finding food, reproduction, and avoiding the predators.
Therefore, the correct option is A.

Read the information below then answer the questions which follow:
To grow, plants require water. They cannot get this water unless it is available in the soil. Plants
obtain water from the soil through their roots. It then passes up the stem and to the leaves and
flowers. The plant does not take all the water available in the soil. Much of the remaining water
evaporates into the surrounding air.
In an experiment, a stem which contained several flowers were placed in a beaker of water
containing red ink.

The meal Valerie is planning to eat at dinner has total 800 Calories. If 55% calories come from carbohydrate, 20% from fat and 25% from proteins, calculate the amount of carbohydrates, fats, and proteins (in grams) in the meal.
Answer:
Carbohydrate = 57.023g
Fats = 20.736g
Proteins = 25.919g
Explanation:
According to this question, Valerie is planning to eat at dinner meal that has a total of 800 Calories.
- 55% calories come from carbohydrate i.e. 55/100 × 800 = 440 calories
- 20% calories come from fat i.e. 20/100 × 800 = 160 calories
- 25% calories come from proteins i.e. 25/100 × 800 = 200 calories
Since 7.716 calories = 1g
1. Amount of carbohydrates in gram = 440/7.716 = 57.023g
2. Amount of fats in gram = 160/7.716 = 20.736g
3. Amount of proteins in gram = 200/7.716 = 25.919g
All of the following are true of spermatogenesis EXCEPT: Question 18 options: DNA replicates once, but cells divide twice. The products are spermatozoa that each have a head, midpiece and tail. Spermatids containing 23 chromosomes (1n) are produced. One spermatogonium produces 4 spermatids Genetically diverse spermatids are created.
Answer:
One spermatogonium produces 4 spermatids FALSE. One primary spermatocyte produces 4 spermatids.Explanation:
Germ cells are diploid reproductive cells in charge of gamete production. Germ cells divide by mitosis and meiosis. Through mitosis, they originate more sexual cells, but through meiosis, they produce gametes -sperm and egg cells-. This process is known as gametogenesis.
Gametes´destiny is to merge during fecundation, and a new diploid cell called zygote emerges through fertilization. The zygote is a complete cell and suffers successive mitosis to form the new organism.
Spermatogenesis is the process of production and maturation of sperm cells. Spermatogonia are the masculine diploid germ cells, carrying 46 chromosomes. These germ cells suffer mitosis to reproduce. Some of them stay as spermatogonia, and some others become primary spermatocytes, which are in charge of gamete production. Primary spermatocytes are also diploid cells, meaning that they still carry 46 chromosomes.
Each primary spermatocyte replicates its genetic material and then goes through meiosis I to produce two daughter haploid cells called secondary spermatocytes, each of them carrying 23 chromosomes. Each secondary spermatocyte will produce two other haploid daughter cells by meiosis II.
The total result from the two cellular divisions of each primary spermatocyte is four haploid daughter cells called spermatids.
During spermiogenesis, spermatids mature into spermatozoa or sperm cells. Each sperm cell characterizes by being composed of a head, midpiece, and tail.
DNA replicates once, but cells divide twice TRUE The products are spermatozoa that each have a head, midpiece, and tail TRUE Spermatids containing 23 chromosomes (1n) are produced TRUE One spermatogonium produces 4 spermatids FALSE. One primary spermatocyte produces 4 spermatids.Genetically diverse spermatids are created TRUEwhere is plants respiration takes place?
Answer:

Which of the following is a characteristic of the plasma membrane?
To protect the cell's internal contents, water is the only substance that can freely pass through the plasma membrane.
Only small molecules are allowed into and out of the cell by the plasma membrane.
Its selective permeability allows certain molecules, such as oxygen and carbon dioxide, to flow freely in and out of the cell while controlling the flow of other molecules.
The structure of the phospholipids forms a stiff protective outer shell around the cell's internal contents.
Answer:
The plasma membrane forms a barrier between the cytoplasm and the environment outside the cell. A main characteristic of the plasma membrane is selective permeability
The following is a characteristic of the plasma membrane: Its selective permeability allows certain molecules, such as oxygen and carbon dioxide, to flow freely in and out of the cell while controlling the flow of other molecules, which is the third option.
What is the importance of the plasma membrane in cells?The plasma membrane acts as a barrier in the cell, controlling the movement of molecules as well as some gases such as oxygen, carbon dioxide, and water that pass through it but not larger and more polar molecules. The importance of this is that it regulates and controls the inflow and outflow of substances such as hormones, etc.
Hence, the following is a characteristic of the plasma membrane: Its selective permeability allows certain molecules, such as oxygen and carbon dioxide, to flow freely in and out of the cell while controlling the flow of other molecules, which is the third option.
