A steroid hormone approaches its target cell. Which will happen first?
The hormone will enter the nucleus
The hormone will combine with proteins to form lipoproteins
The hormone and its receptor will interact with the DNA
The hormone and its receptor will enter the cell’s nucleus
Answers
A steroid hormone approaches its target cell, therefore the hormone will enter the nucleus and is what will happen first which is therefore denoted as option A.
What is a Hormone?This is referred to as a chemical messenger which is released directly into the bloodstream and is responsible for the control of certain metabolic reactions occurring in the cell and an example is steroid hormone such as androgens.
In a situation whereby a steroid hormone approaches its target cell, it first passes through the plasma membrane before it then becomes adhered to the receptors which are present in the nucleus or cytoplasm.

d.Animal cells plasmolyse in a concentrated sugar solution.
Pls i really need help
And thanks later!!
Answers
B) In the option B, the cell wall stops water getting into the cell that is wrong. After a plant cell is immersed in pure water, water enters by osmosis. However, the relatively inelastic cell wall will expand, and it exerts a back pressure on the cell. The back pressure is called turgor pressure which opposes further water uptake.
C) In the option C, the partially permeable cell wall is wrong. The characteristics of cell walls is full permeability.
D) In the option D, animal cells plasmolyse that is wrong.
The phenomenon of plasmolysis is found in the cell with cell walls such as plants, fungi, and bacteria. Animal cells are not surrounded by cell walls, so plasmolysis does not be found in animal cells.

List the quality control measures taken to ensure contamination does not occur during the Chelex extraction process (DNA extraction) and give reason
Answers
Answer and Explanation:
To promote a good DNA extraction through the Chelex extraction protocol, it is important to follow some measures, which are essential for the entire process to take place efficiently.
The most important measure is to avoid contamination. In this case, all surfaces, container and substances used must be properly sterilized, preventing unnecessary elements from coming into contact with the DNA sample or the protocol reagents.
It is important that the researcher is wearing clean, appropriate clothing and gloves when using this protocol. This avoids impurities and contamination with the researcher's DNA.
Another precaution must be taken with the DNA sample and the reagents that will be used during the extraction. All must be stored correctly, preventing their degradation, especially the DNA, which is a very unstable molecule.
Finally, the researcher must strictly follow all the steps of the protocol as indicated.

HELP PLEASE Name any two of the major types of chemical substances that are broken down in chemical digestion. For each substance, name an enzyme that breaks them down and what final product is actually absorbed by the body for use or storage.
Answers
Two major types of chemical substances that are broken down in chemical digestion are carbohydrates and proteins. Carbohydrates are broken down by the enzyme amylase, which is found in saliva and the pancreas.
Proteins are broken down by a group of enzymes called proteases, which are produced by the stomach and pancreas. Proteases break down proteins into smaller peptides and individual amino acids, which can be absorbed by the body and used to build new proteins or as a source of energy. Overall, the breakdown of carbohydrates and proteins in chemical digestion is crucial for the body to obtain the nutrients it needs for energy, growth, and repair. Amylase breaks down complex carbohydrates into simpler sugars, such as glucose and fructose, which can be absorbed by the body and used for energy or stored as glycogen in the liver and muscles.

What are the stages of bee development (eggs,larvae,pupae)
Answers
The stages of bee development are egg, larva, pupa, and adult. Eggs hatch into larvae, which then transform into pupae. Finally, adult bees emerge and undergo further maturation.
The stages of bee development are:
1. Egg: The bee life cycle begins when the queen bee lays an egg in a honeycomb cell.
2. Larva: The egg hatches into a larva, which is a legless, grub-like creature. The larva is fed a special diet called royal jelly, which stimulates its growth.
3. Pupa: The larva undergoes metamorphosis and transforms into a pupa. Inside the sealed cell, the pupa undergoes various changes, developing into an adult bee.
4. Adult Bee: After completing the pupal stage, the fully developed adult bee emerges from the cell. The bee then undergoes further maturation, such as its exoskeleton hardening, wings expanding, and adult coloration appearing.
It's important to note that there are three castes of bees: queen, worker, and drone. The development process for each caste is similar, but the diet and size of the cells they are raised in differ, leading to their distinct roles within the colony.

One way that deposition by gravity slowly changes Earth’s surface is by creating talus slopes. Talus slopes are piles of rock fragments that accumulate at the base of cliffs when rocks break away from the cliff face and fall, bounce or roll downslope. Talus slopes are common in areas that experience freeze-thaw weathering, which causes chunks of rock to lose contact with the cliff face and fall. Talus slopes can affect the shape and stability of the landforms they cover, as well as the vegetation and wildlife that live on them.

Describe one way an organism can grow other than increasing in size
Answers
Answer and Explanation: Growth can be classified into two categories in living organisms. It is vegetative and reproductive growth.
Biologically, other than growing in size, any organism will show reproductive growth. Be it a plant, animal, fungus, or any other microorganism, all of them show reproductive growth.
In the biological world, there are four main types of reproductive growth. They are vegetative reproduction, asexual reproduction, sexual reproduction, and parthenogenesis. Like size growth, reproductive growth can also be logarithmic, or exponential.
Hence, reproductive growth is another very important form of growth other than the size of the body. Reproduction ensures the continuity of the generation and maintenance of species. Reproductive growth also helps to bring in genetic variation and ensure survival due to mutation.

Spinal Cord is the tube-like structure which consists of bundles of nerve fibers. It is covered by the meninges and is surrounded by the cerebrospinal fluid.
Backbone or the spinal column is the central axis of the skeleton in all vertebrates. In a newborn human, there are about 33 bones that make up the spinal column. By the time the newborn becomes an adult, the number of bones reduces to 24 as they fuse during normal growth and development.
Moreover, the spinal cord is protected by the spinal column. In this article, we shall explore more differences between the two:
