Answer:
Chromosome number in gametes- haploid (n)
Chromosome number in zygote- diploid (2n)
Explanation:
Sexually-reproducing organisms make use of gametes to reproduce. The gametes are produced via the process of meiosis, which is a cell division that results in daughter cells (gametes) that have their chromosomal number reduced by half. A diploid (2n) organism i.e. possess two set of chromosomes undergoes meiosis to produce haploid (n) gametes i.e. contains one set of chromosomes. The male parent produces haploid sperm while the female parent produces haploid egg.
During reproduction, these haploid gametes (sperm and egg) combine in a process called FERTILIZATION to produce a diploid ZYGOTE. The diploid zygote then divides and grows into the full organism. Hence, since a zygote is formed by the fusion of two haploid gametes (sperm and egg), it contains a diploid chromosome number i.e. sperm (n) + egg (n) = zygote (2n)
5. The function of the leaf cuticle is:
a. photosynthesis b.gas exchange
c. waterproofing
d. secretion
Answer:
c. waterproofing
Explanation:
Cuticle is a waxy layer present on the surface of leaves. The main function of cuticle is to reduce the rate of transpiration in the plant body. Transpiration is process in which water is removed from the body of plants through leaves and body parts. About 98 % of water is lost in transpiration. So for reducing the loss of water in plants through transpiration, cuticle is the only tool for plants.
Which part of the brain receives sensory stimuli and passes along the information to the other parts of the brain?
Answer:
The Hypothalamus
Explanation:
This is a tiny part of the brain located at the forebrain, right above the pituitary glands. This tiny body regulates temperature control, thirst and sleep. It collects data from other parts of the brain and sense organs through nerve impulses. It acts as the link between the nervous system and the endocrine system.
The hypothalamus monitors the temperature of the blood that passes through it to detect any change in the body temperature. It also receives information about temperature changes in the external surroundings from thermoreceptors messages sent from the skin.
what is a lymph node
Answer:
A small bean-shaped structure that is part of the body's immune system. Lymph nodes filter substances that travel through the lymphatic fluid, and they contain lymphocytes that help the body fight infection and disease.
Explanation:
Answer:
Lymph node, any of the small, bean-shaped masses of lymphoid tissue enclosed by a capsule of connective tissue that occur in association with the lymphatic vessels.

(A) They move faster on average.
B They are vibrating.
© They have less average energy.
D They move more freely.
Answer: they are vibrating
Explanation: During conduction, heat is transferred through the vibration of molecules in a substance. As something gets warmer, it begins to increase the vibration and movement of the molecules that it consists of
Final answer:
In the colder math classroom, the air particles c) have less average energy and therefore move slower compared to the warmer science classroom, where particles move faster due to higher kinetic energy.
Explanation:
Luciana notices that the air in her science classroom is much warmer than the air in her math classroom. The difference in the temperature of the air can be explained by the behavior of the air particles. In the colder math classroom, the c) air particles will have less average energy compared to the warmer science class. Air particles in a warmer environment move faster on average due to higher kinetic energy. Thus, as the particles in the math classroom are part of a colder environment, they move slower than those in the warmer science classroom.

photosynthesis is a set of ________ in which ________ energy is converted to ___________ energy
Answer:
Photosynthesis is a set of reactions in which solar energy is converted to chemical energy
Explanation:
Photosynthesis is a biological process where light energy is converted into chemical energy in the form of glucose. It occurs in two stages: light-dependent and light-independent reactions. The process is vital for the survival of plants and many other organisms.
Explanation:Photosynthesis is a set of chemical reactions in which solar (light) energy is converted to chemical energy. As a fundamental biological process, photosynthesis occurs in plants and some other organisms, absorbing solar energy from the sun, which is then converted into stored chemical energy in the form of glucose and other carbohydrates.
The process of photosynthesis consists of two main stages: the light-dependent reactions and the light-independent reactions (sometimes called the Calvin Cycle). During the light-dependent reactions, energy from sunlight is absorbed by pigment molecules (mainly chlorophyll) and converted into ATP and NADPH. These serve as temporary storage for the energy and are used in the second part of photosynthesis: the light-independent reactions. Here, using the energy from ATP and NADPH, carbon dioxide and water are converted into glucose, which is a form of energy that the plant can use.
Thus, photosynthesis transforms light energy, which is not directly usable by plants, into chemical energy in the form of glucose. This glucose can then be used by the plant for growth and reproduction, or consumed by other organisms, transferring the chemical energy through the food chain.

In which situation would artificial insemination most likely be used over other forms of treatment?
OA.
A woman's ovaries do not release any eggs.
OB.
A man's testicles have not properly descended, lowering sperm count.
OC.
There is a blockage in the fallopian tubes.
OD.
The mucus that helps the sperm travel to the uterus is too thick.
Artificial insemination is most appropriate for situations where a man has a lower sperm count due to undescended testicles. It is a form of assisted reproductive technology (ART) that can help overcome male factor infertility by using concentrated sperm.
Explanation:In the context of assisted reproductive technologies (ART), artificial insemination would most likely be used over other forms of treatment in the case where a man's testicles have not properly descended, lowering sperm count (Option B). This is because artificial insemination can utilize sperm that have been collected and concentrated to increase the chances of fertilization when low sperm count is an issue. In cases where a woman's ovaries do not release any eggs, blockage in the fallopian tubes, or thick uterine mucus, other forms of ART such as in vitro fertilization (IVF) or surgical intervention may be more appropriate.
Treatments for infertility are highly dependent on the underlying cause. When the issue is related to sperm production or the availability of sperm, artificial insemination is often the first line of action. In contrast, for blockages or issues with egg release, surgical procedures, hormonal treatments, or advanced procedures such as IVF may be recommended.

The two major cell types in a sponge's tissues are
collar cells and epithelium.
O collar cells and amoebocytes.
amoebocytes and oscula.
epithelium and oscula.
Answer: B. collar cells and amoebocytes
The collar cells have a funnel like collar and a flagellum. Collar cells whip their flagella to make water go through the sponge. Then the water brings nutrients and oxygen, while while also taking out waste and carbon dioxide.
Amoebocytes first deliver nutrients from choanocytes to the other cells, giving rise to eggs. Then they bring phagocytized sperm from choanocytes to eggs.
In sponges, the major cell types are collar cells and amoebocytes. Collar cells help capture and digest food, while amoebocytes handle nutrient transport and differentiation into other cell types. Option b is correct.
Collar cells have whip-like flagella that create water currents and trap food particles with their collars, which they then digest. Amoebocytes, which move through the mesohyl in an amoeba-like manner, have multiple functions including transporting nutrients from collar cells to other cells, generating eggs for sexual reproduction, and differentiating into various specialized cell types such as collencytes and lophocytes, which help maintain the structure of the mesohyl.Complete question as follows:
