sperms are gametes (reproductive cells) which have half the number of chromosomes (22 autosomes +1 sex chromosome) .Those cells have 23 chromosomes only as their nucleuse fuses *during fertilization* with the ovum's nucleuse which has 23 chromosomes as well . Also it has a special structure which makes it adapted for movement since it's a mobile cell

Answer:

C and E

Explanation:

The key feature here is that individuals cannot evolve. Individuals are either adapted in their movement. This is how evolution by means of natural selection occurs.

The statements which can be formed using the given terminology are: Individuals have different genetics, leading to the evolution of populations. Individuals with adaptations are based on genetics, allowing for populations to undergo evolution. Thus, the correct options are C and E.

Evolution can be referred to as the change in heritable characteristics of biological populations over the period of successive generations. These characteristics are the expressions of genes, which are passed on from the parents to their offspring during the process of reproduction.

The statements which can be formed using the given terminology include: 1. Individuals have different genetics, leading to the evolution of populations. 2. Individuals with adaptations are based on genetics, allowing for populations to undergo evolution

The statement which is true about biodiversity on Earth is that there are more categorized than uncategorized species on Earth. Thus, the correct option is A.

Biodiversity may be defined as the sum total of all living organisms found on the earth.

On Earth, there are about 8.7 million species found in which 95% of them are categorized but approximately 5-6% of the remaining are still uncategorized.

Insects have the highest number of species found in nature. It alone has over 7 lakhs of species.

Because when they is glucose in a patient's urine it means that the patient has diabetes or are too many carbohydrate in his or her blood

if a patient eat too much food containing carbohydrates ,the digestive system breaks down the digestible one into sugar which enters the blood. As blood sugar level rises ,the pancreas produces insulin(a hormone that prompt cells to absorb blood sugar for energy or storage)

Answer:

Glucose

Explanation:

The brain is an energy-hungry organ. Despite comprising only 2 percent of the body’s weight, the brain gobbles up more than 20 percent of daily energy intake. Because the brain demands such high amounts of energy, the foods we consume greatly affect brain function, including everything from learning and memory to emotions.

Just like other cells in the body, brain cells use a form of sugar called glucose to fuel cellular activities. This energy comes from the foods we consume daily and is regularly delivered to brain cells (called neurons) through the blood.  

Studies suggest the quality of the foods consumed over a lifetime affects the structure and function of the brain. For instance, the consumption of omega-3 fatty acids found in fish provides structural material to maintain neurons. Studies also suggest omega-3 fatty acids are essential for the transmission of information between brain cells. In contrast, foods that are rich in sugars and saturated fats have been found to promote oxidative stress, which leads to damage to cell membranes.  

The food you eat also affects molecules in the brain that support cognition. Some foods, such as those with turmeric, support cognition by helping to maintain molecular events related to energy metabolism.

Recent studies suggest lifestyle choices that affect the metabolism of nerve cells, such as diet and exercise, may in some cases provide a non-invasive and effective strategy to counteract neurological and cognitive disorders.

Penguins are water-adapted birds; they have both structural and behavioral adaptations that allow them to thrive in the water, and having oily fur is one of these adaptations that is present in Option A.

There are many adaptations of aquatic animals, such as the adaptations of birds, such as the dolphin and other sea birds, and some of them have webbed feet that help them on the water surface, while others have oily fur that does not come into contact with the water, allowing the bird, such as a penguin, to swim on the water.

Hence, penguins are water-adapted birds; they have both structural and behavioral adaptations that allow them to thrive in the water, and having oily fur is one of these adaptations that is present in Option A.

Answer:

No.

Explanation:

There are two strands in DNA -i)Leading strand

ii)lagging strand.

Replication of the leading DNA strand is continuous, while replication along the lagging strand is discontinuous. After a short length of the DNA has been unwound, synthesis must proceed in the 5' to 3' direction; that is, in the direction opposite that of the unwinding.

No, we will not be able to synthesize both strand of the dna helix in a continuous manner because the lagging strand synthesize in a discontinuous manner.

The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication. All living things replicate their DNA, which is the most crucial component of biological inheritance.

Continuous DNA synthesis takes place on the leading strand. As the helix unwinds, DNA synthesis on the lagging strand restarts numerous times, resulting in numerous brief pieces known as "Okazaki fragments," which are then joined by DNA ligase to form a single DNA molecule.

Different oganelles do their own function.

The structures of organelles differ because the structures of  organelles are related to their functions.

An organelle is a subcellular structure that has one or more specific functions in a cell, such as an organelle in the body. The most important cell organelles are the nuclei, which store genetic information.

Organelles are small structures in the cytoplasm that perform functions necessary to maintain homeostasis in the cell. They are involved in many processes, such as energy production, the formation of proteins and secretions, the destruction of toxins, and responding to external signals.

Examples of membrane-bound organelles include the nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, plastids, lysosomes, and vacuoles.

S. aureus is indeed gram-positive but within the bacteria classed as gram-positive, there are differences that might predispose them to infection by phages.

S. aureus as an organism usually adapts to their environment through mutations on their membranes which can be proteins e.g. surface proteins, or receptor molecules e.g. sugar receptors.

In preventing invasion by phages, mutations are gained that prevents attachment to the bacteria cell surface. This effectively prevents the binding of the phage to the bacteria thus preventing infection.

It is also worthy to note that the differences in bacteria strain could range from a few nucleotides to large variations in chromosomes and thus can aid in identifying specific strains that might have beneficial factors in the context of disease prevention.
