Why is it that dominant diseases are not as common as recessive ones?
Answer:
Mainly because if a disorder is dominant, then it will be manifested by all who have the gene. If the disorder is severe, then it will reduce the chances of the individual surviving to grow up and reproduce (unless the disorder only manifests symptoms in later life). If they do reproduce, then 50% of their offspring will inherit the gene, and be at a similar disadvantage in reproduction. Thus, there is likely to be selection against the gene. By contrast, a recessive disorder is only manifested if both parents pass on the abnormal gene, and an individual with one gene for the disorder is usually at no disadvantage. Thus, there is much less selection against abnormal recessive disorders.
What stage of cell respiration is being shown above?
The stage of cell respiration that is being shown above is oxidative phosphorylation. During this stage, the transport of electrons is coupled to the generation of an electrochemical gradient.
Cellular respiration can be defined as a series of metabolic reactions by which aerobic cells generate energy in the form of ATP.
Cellular respiration has three main stages: glycolysis, the Krebs cycle and oxidative phosphorylation.
During oxidative phosphorylation, the transport of electrons across the mitochondrial membrane is coupled to the generation of an electrochemical gradient, which is then used to generate ATP by an ATP synthase as shown in the figure.

write types of cellular respiration and their function?
Answer:
There are 2 types of cellular respiration i)Aerobic respiration
ii)Anaerobic respiration
Explanation:
i)Aerobic respiration: is the chemical reactions in the cells that use oxygen to break down food molecules to release energy. Its complete oxidation process that releases more energy (2830 $ J). The word equation of aerobic respiration is:-
glucose + oxygen------> carbon dioxide + water + energy.
ii) Anaerobic respiration: is the chemical reactions in cells that break down food to release energy without using oxygen. Its partial (incomplete) oxidation process that release a few energy (188 $ J) The word equation of anaerobic respiration in human muscles:-
glucose-----> lactic acid
The word equation of anaerobic respiration in yeast:-
glucose yeast alcohol + carbon dioxide

why are the offspring of coral identical to the parent
they reproduce sexually so offspring have increased genetic variation
they reproduce asexually so offspring have increased genetic variation
they reproduce sexually so offspring have decreased genetic variation
they reproduce asexually so offspring have decreased genetic variation
Answer:
they reproduce asexually so offspring have decreased genetic variation
Explanation:
when an organism reproduces asexually, its offspring will look identical to the parent due to the offspring only receiving genes from one parent. I hope this helps!
Give reasons :
a) Nylon clothes should not be worn in the kitchen.
b) Cotton fibre is used to make bath towels.
c) Umbrellas and raincoats are made from synthetic fibres
Answer:
a) It is dangerous to wear nylon clothes while cooking because it is a synthetic cloth and they catch fire easily also they can stick on our body which is very painful.
b) Cotton is a natural product. And unlike synthetic fibres, it is more absorbent. The towel hence has high absorbency.
c) Nylon and polyester are two fabrics most commonly used in raincoats and umbrellas. They are not absorbent the way natural fibers are. They naturally resist waterlogging, and can be made waterproof.
rough endoplasmic reticulum what is and function
The general function of the endoplasmic reticulum is to produce protiens for the cell to function. The rough ER in particular has many ribosomes on it's surface, while the smooth ER does not. These ribosomes give the rough ER it's distinct appearence under a microscope, and assist in making protiens.

The individual blades are called leaflets. The leaflets are also referred to as
foliole.
The leaflets is referred to as the individual leaf and is usually not attached
directly to the main stem of the plants.
A simple leaf has only one blade while a compound leaf has two or more
blades which are divided into parts which we call leaflets. Leaflets are
usually in groups in plants and can be plucked individually from the
branches of trees.

Which of the following best describes how the amount of DNA in the cell changes during M phase?
The amount of D N A doubles as the D N A is replicated.
The amount of D N A slightly increases as a result of new organelle synthesis.
The amount of D N A does not change while the cell grows.
The amount of DNA is halved as the cell divides into two daughter cells.
Answer:
The amount of DNA doubles as the DNA is replicated
Explanation:
on the graph it shows that the DNA is x2 by the time it reaches G2
The amount of DNA is halved as the cell divides into two daughter cells. Therefore, option (D) is correct.
What is M phase?M phase, also known as mitosis, is the phase of the cell cycle in which a cell divides into two daughter cells. M phase is divided into several stages, including prophase, prometaphase, metaphase, anaphase, and telophase. During prophase, the cell's nucleolus disappears and the chromatids (replicated chromosomes) become visible. In prometaphase, the nuclear envelope breaks down and the mitotic spindle begins to form.
During metaphase, the chromosomes line up at the equatorial plane of the cell. In anaphase, the sister chromatids are separated and move to opposite poles of the cell. Finally, in telophase, two new nuclei form and a new cell wall begins to grow between the two daughter cells. Overall, M phase is a crucial step in the cell cycle that ensures the accurate segregation of genetic material to the daughter cells.

Imagine that the climate in your region became extremely arid, and freshwater became a scarce and precious resource. Wasteful uses of water, such as watering lawns and filling swimming pools, would be strictly outlawed, and water from the municipal water supply would cost 100 times what it does now. Discuss how you would adapt to that situation.
I would adapt to such situation by ensuring that physical activities are
reduced , use of water is adjusted and recycling is maximized.
Water is a n important component of life as we need water for various
activities such as drinking, cooking, washing etc. Scarcity of water can result
to unhygienic conditions and dehydration which could result in death.
it is best to ensure physical activities are reduced to prevent dehydration
through sweating. The wastage of water should be reduced to the barest
minimum through use adjustment and recycling.

What does it mean for a bacteria or protist to be photosynthetic?
O They are responsible for disease growth.
o They are only responsible for the decomposition of compost.
They are a primary producer of biomass in the ocean.
They are multi-cellular organisms.
If a bacteria or protist is photosynthetic that means they are the primary producer of biomass in the ocean.
What are primary producers?Primary producers are organisms that produce their own food through the process of photosynthesis or chemosynthesis. These organisms are the base of the food chain in most ecosystems, as they provide the energy that drives the ecosystem.
Photosynthetic primary producers, such as plants, algae, and some bacteria, use energy from sunlight to convert carbon dioxide and water into glucose, a type of sugar. They release oxygen as a byproduct of this process.
Chemosynthetic primary producers, such as some types of bacteria, use energy from chemical reactions to convert inorganic substances into organic matter. These reactions typically involve the oxidation of sulfur compounds or methane, and they occur in environments where sunlight is not available, such as deep ocean vents and underground coal mines.
Primary producers are important because they provide the energy that drives the food chain and support the rest of the ecosystem. Without primary producers, higher-level consumers, such as herbivores and carnivores, would not have a source of energy.
