What is difference between nervous and chemical(endocrine) system???
Answer:
Endocrine system uses chemical signaling (hormones produced by glands) while the nervous system uses electrical signaling (neural impulses).
Answer:
The differences are given below ↓
Nervous System
Electrical impulses are the messengers in the nervous systemBrain and the spinal cord constitute the nervous systemNerve impulses are transmitted through neuronsThe nervous system is under both voluntary and involuntary controlNerve impulses make use of the neurotransmitters at synaptic clefts and sodium and potassium channels and enter the target cellsResponses are localisedChemical (Endocrine) System
Hormones are the chemical messengers in the endocrine system that target cells through the bloodstreamGlands and organs like thyroid, pituitary glands and reproductive organs (ovaries and testes) are involved in the endocrine systemHormones are transmitted through blood vesselsThe endocrine system is under involuntary controlThe hormones enter into the target cells by diffusing through the plasma membrane or by binding to the cell receptorsResponses are widespread

Indicate differences between oogenesis and spermatogenesis 1. final number of gametes produced 2. timing of meiosis II 3. timing of onset of prophase I 4. final number of chromosomes in the mature gamete
The correct options indicating the difference s between oogenesis and spermatogenesis are;
1) Final number of gametes produced.
2) Timing of Meosis 2
3) Timing of onset of prophase 1
Oogenesis is process by which a diploid germ cell known as an oogonium which is found in the fetal ovary thereafter becomes a haploid ovum in the adult species after fertilization must have taken place.
During the initial stage of oogenesis,the diploid germ cell moves from the yolk sac to the fetal ovary from there, further mitotic division will occur.
Spermatogenesis on the other hand is simply the process by which haploid spermatozoa get developed from germ cells and finally to sperm production,this occurs in the seminiferous tubules of the testes.

Explain how and why a drop of syrup can spread through the water in a beaker without stirring?
Answer:
The syrup drop spreads in water without stirring because particles of syrup separate water molecules and bump into it and dissolve.
Explanation:
Answer:
The syrup drop spreads in water without stirring because particles of syrup separate water molecules and bump into it and dissolve.
Explanation:
This is called diffusion. If you just leave the drop of syrup in the beaker for a while, it will eventually spread out around the beaker and all of the water will become sweet.
For example:
This is just like a restaurant, there is non-smoking half of the restaurant and there is a smoking half. The smoke will eventually spread out front he smoking corner to the non-smoking corner.
Another example:
If you pee in the pool, the pee will eventually spread out through the pool.
horizontal gene transfer can occur through several mechanisms. why is this relevant to humans
Answer:
Explanation:
Horizontal gene transfer helps in acquiring relevant gene that are not present in cell but are beneficial.
If a gene is lost in the cell, through gene transfer it can be regain and the various adverse effect caused through the absence of the gene can be reversed.
It also help in treatment of various disease such as cancer by introducing into the body non cancerous cells and prevent the spread of cancerous cells .

Which of the following is not found in all cells?
Cell membrane
Genetic material
Cytoplasm
Cell wall
Answer:
option D is correct
Explanation:
cell wall is not present in all cells because it is present in plant cell but not in animal cell
Cell wall is the structure that is not found in all cells, only in bacteria and plant cells where it is attached to the plasma membrane on the outer surface.
What is a cell wall?A cell wall is a rigid structure that lies outside the plasma membrane and protects the contents of the cells of algae, fungi, plants, bacteria, and archaea.
Characteristics of a cell wallIt can be a layer of chitin (in the case of fungi), cellulose (plants), peptidoglycan (bacteria), or other materials.It is responsible for protecting the contents of the cell and absolute rigidity to the cell structure.Therefore, we can conclude that the cell wall is what covers prokaryotic cells and plant cells.

Describe the differences between the sporophyte and gametophyte generations of seedless tracheophyte plants and be sure to discuss structures and ploidy.
Answer and Explanation:
Tracheophyte plants, also known as vascular plants, are those that possess a supportive tissue that can also conduct fluids -The Xileme- and another tissue that conducts nutritious elements produced by photosynthesis -The Phloem-. These plants have a root (basically underground), a stem (aerial), and leaves. All of them together form the corm. And the corm counts with these vascular tissues to which we referred before.
There are different types of Tracheophyte plants, some of them produce seeds to reproduce and disperse -Spermatophyta- and some others reproduce and disperse by spores -Pteridophyta-. This last seedless group corresponds to ferns and other similar plants.
Pteridophytes characterizes for having a sporophyte that has stems with leaves and a root. It also has primitive xylem composed by tracheids and phloem, both of them formed by vascular bundles located in a central cylinder.
Spores are its dispersion units and are responsible for colonizing new areas. They also constitute the resistance units under extremely unfavorable conditions.
Their life cycle is composed of the asexual phase (sporophytic phase) and the sexual phase (gametophytic).
The sporophyte, the dominant asexual generation, it is a perennial and diploid structure. Its aerial part might disappear during unfavorable seasons, but it reappears during spring or summer. The sporophyte is in charge of asexual reproductionThe gametophyte, instead, is and haploid structure, ephemeral and must be in the water for its survival, and for sexual reproduction to be successful. In the presence of water, masculine gametophyte -antherozoids- are released and they swim to the archegonium to meet the ovocell. Antherozoids can swim because they have flagella. After fertilization, a new sporophyte is produced.Which hypothesis is testable?
O Plants that are grown by using brand A fertilizer taste best.

scientist adds energy to a
block of metal. According
to the kinetic theory, what
should the scientist predict
will happen to the metal?
Answer:
According to the kinetic energy, the atoms of the metal will become very energetic and will tend to vibrate more within their lattice structure.
As the atom becomes more energetic the atoms become more and more energetic tending to wriggle free from the crystalline metallic structure making the metal more malleable.
With the addition of more energy, the atoms of the metal will become more energetic than the inter atomic metallic bond and the metal starts to melt into liquid metal.

I'm not so sure.
Auxin is a plant growth hormone (phytohormone) which is responsible for the cell division and large amounts of auxin inhibits the growth of roots in plants. Thus, the correct option is C.
What is Auxin?
Auxins are a class of phytohormones which show some morphogen-like characteristics. Auxins play the main role in coordination of growth and behavioral processes in plant life cycles. These are essential for the development of plant body.
Auxin is a key regulator of growth and development in plant, cell division, elongation and differentiation, development of embryo, root and stem tropisms, apical dominance, and flowering in plants.
In the shoots, auxin hormone stimulates cell elongation and the presence of high concentrations of auxin in plants promote growth. However, in the roots auxin hormone inhibits the cell elongation and therefore high concentrations of this hormone limits growth in plants.
