Answer:
The possible genotype is Ff
Explanation:
The possible genotype of the heart cells of such individual would be Ff.
Meiosis usually results in the formation of daughter cells with haploid number of chromosomes from parent cells with diploid number of chromosomes. The chromosomes in the parent cells are usually halved in the daughter cells.
The cells of the heart will have diploid number of chromosomes because they are vegetative cells while the sperm cells will usually have haploid number of chromosomes because they are sex cells.
Consequently, the heart cells of an individual will contain twice the chromosome number present in the sperm cells of such individual.
Hence, if meiosis results in the formation of sperm cells with F and f genotypes in an individual, it simply means that any diploid cell in that individual will have the Ff genotype.
The possible genotype is Ff
The following information should be considered:
Meiosis normally arise when the daughter cells are created along with haploid number of chromosomes from parent cells with diploid number of chromosomes. The chromosomes in the parent cells are normally halved in the daughter cells. The heart cells should have diploid number of chromosomes since they are vegetative cells while on the other hand the sperm cells will normally have haploid number of chromosomes. Due to this, the heart cells of an individual will comprise of twice the chromosome number that are present in the sperm cells of such individual.

Explain the plasma membrane in easy way.
Answer:
The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment.[1][2] The cell membrane consists of a lipid bilayer, including cholesterols (a lipid component) that sit between phospholipids to maintain their fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that go across the membrane serving as membrane transporters, and peripheral proteins that loosely attach to the outer (peripheral) side of the cell membrane, acting as enzymes shaping the cell.[3] The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.[4] In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled.[

What is the correct term for splitting an atom to release nuclear energy?
Splitting the nucleus of an allom to release energy is referred to as nuclear
Answer:
The splitting of a uranium atom releases energy. This process is called “nuclear fission”, since the centre of an atom is called its nucleus. When a uranium atom splits it gives off more neutrons, which can then split more atoms, and so the energy level rapidly multiplies
Explanation:
The splitting of a uranium atom releases nuclear energy by the process called nuclear fission, releases more neutrons, which can then split atoms, and energy level multiply rapidly.

Some parts of the worlds rainforests haven’t been studied closely, and may contain species of plants which have benefits for humans. ‘Suggest and explain uses of stem cells taken from the meristem of a new species of plant.’
To determine the similarity of stem cells of one species of plant with that of another: By determining the similarity between the stem cells taken from two different species, it can be identified whether there is a possibility of clowning, of giving birth to new and improved species of plants that are beneficial for mankind, or that of interchanging the stem cells to boost up or slow down the growth of the plants. To determine whether the stem cells can be altered and reintroduced to make the plants grow in a specified manner: By altering and modifying the stem cells and reintroducing them back again, it is possible to restrict the growth of the plant to a specific size or shape. This trait of the stem cells can be used to make the plantation possible in compact areas as well as to grow the plants in the desired shapes.
To determine whether the speed of division of cells at the roots and appendages of the plant can be modified: By restricting or boosting the speed of the division of meristem cells using modified stem cells, the plant can be made to grow faster in a specific season and slower in another. This feature can be used to lower the vulnerability of the plant species towards various natural weathering actions.
Stem cells extracted from the meristem can be precisely examined for their effectiveness against illnesses that harm portions of the plants such as the roots, shoots, and appendages to ascertain the resistance against various plant diseases.
What is meristem?They can thus also be utilized to rebuild the damaged plant tissues if the newly discovered species becomes extinct.
It can be determined whether there is a chance of clowning, or of giving birth to new and improved species of plants that are beneficial to mankind.

Which are examples of active transport across the cell membrane? a. osmosis and diffusion b. diffusion and facilitated diffusion c. osmosis and chemiosmosis d. endocytosis and exocytosis
Answer:
d. endocytosis and exocytosis
Explanation:
These processes bring specific items in/out of the cell through active transport since the particles being brought in are generally large. Water for example, a much smaller particle, would use passive transport through the process of osmosis. Hope this helps!
Endocytosis and exocytosis are examples of active transport across the cell membrane.
Active transport is the movement of substances in and out of the cell through the membrane using energy and occurs against a concentration gradient.
Endocytosis is called the process by which cells incorporate into them molecules, large or small, that cannot pass through the cell membrane.An example is the endocytosis of the complex that is formed between receptor proteins of polypeptide or protein hormones at the level of the plasma membrane.
Exocytosis is the process by which different types of molecules contained in a cytoplasmic vesicle of a cell are secreted outwards.Insulin secretion is done in small pinocytosic vesicles that have insulin in colloidal dispersion, this secretion is in favor of a gradient, since insulin is more concentrated within the cell than in the extracellular space.
Therefore, we can conclude that endocytosis and exocytosis are examples of active transport across the cell membrane.

what causes water to enter plant roots from the soil?
a. water concentration in root hairs and the soil are equal.
b.water concentration in root hairs and the xylem are equal.
c.water concentration in root hairs is higher than in the soil
d.water concentration in root hairs is lower than in the soil
Answer:
D
Explanation:
The cell sap is hypertonic to the soil therefore an osmotic gradient is formed and the roots therefore intake water
What causes water to enter plant roots from the soil is mainly because the concentration of water in the root hairs is lower than in the soil. The correct option would be D.
Water moves from the soil into the root by osmosis.Osmosis is the movement of water molecules from the region of high water potential or concentration to the region of low water potential or concentration.Hence, water will enters the plant roots from the soil because the water potential in the soil is more than that of the root airs.
