Answer:

Once an egg is fertilized by a sperm, a zygote is formed. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation. Cells in these three layers will give rise to different parts of the organism. The endoderm eventually becomes the gut.

Explanation:

- Eijiro <3

A zygote is formed when an egg is fertilized. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation.

This is the process in which cells acquire different structure and function from one another to form distinct cell types.

When a zygote is formed, cell division takes place which helps to trigger differentiation of cells.

There will be 27 chromosomes in each of its gametes.

• Meiosis is also called reductional division, in the process s-ex cells, that is, sperm and egg are produced, and each cell has the half number of chromosomes than its parent cells.

• In the given case, the organism is diploid with 54 chromosomes, that is, 2n = 54.

• Here n is the haploid number of chromosomes, in the given case, n = 27, that is, the haploid number of chromosomes is 27.

• Therefore, the sperm and egg cells have 27 number of chromosomes each.

Thus, the correct answer is option c, that is, 27.

Answer: Passive transport

Explanation: If the direction is from left to right, then it is passive. Passive transport is like unconscious, like osmosis. If I open my lunchbox and I have a peanut butter sandwich, the peanut butter smell (molecules) will naturally spread around and so someone standing next to you will smell it, and someone 3 seats away from you will smell it. Note that it is EVENLY spreading out, so after a while the person sitting 3 seats away from you will smell the peanut butter with a similar intensity as the person sitting next to you. Active transport is doing something forcefully. If the direction was right to left, then it would be active transport. :D

Answer:

A tripeptide

Explanation:

Alanine (Ala), Glycine (Gly) and Valine (Val) are amino acids, i.e., organic molecules that contain at least an amino (–NH2) and one carboxyl (–COOH) functional group. The amino acids held together by peptide bonds, which are formed by a carboxyl group of one amino acid and an amino group of another one, in order to form a peptide. Thus, a tripeptide is a peptide composed of three amino acids joined by two internal (and sometimes three) peptide bonds. In the case above described, the tripeptide formed by the binding of Glycine, Alanine, and Valine can be abbreviated as Gly-Ala-Val (i.e., in this order).

Explanation:

Answer: Neutrophils have a two-lobed or bilobed nucleus, while eosinophils have bean-shaped nucleus and basophils have a multi-lobed nucleus. The lifespan of neutrophils is 5-90 hours, whereas eosinophils lifespan is 8-12 hours and that of basophils have a life span of 60-70 hours. functions- All the granulocytes present in white blood cells play their role in fighting against pathogens and in destroying them, where neutrophils vital role is in engulfing the foreign or toxic particles through phagocytosis; Eosinophils are the first one in triggering the inflammatory response during allergic disorders; and Basophils prevents the immediate blood clotting, as it contains heparin (anticoagulant) in the body. structures- Neutrophils have a two-lobed or bilobed nucleus, while eosinophils have bean-shaped nucleus and basophils have a multi-lobed nucleus. ... Neutrophils make up to 40-75% of the total white blood cells, while eosinophils mark their presence up to 1-6% and basophils are up to 0.5-1% of the whole white blood cells.  stained- Neutrophils:Neutrophils are stained in natural pink color. Eosinophils: Eosinophils are stained in brick red in acidic stains. Basophils: Basophils are stained in dark blue in basic stains. counts- Neutrophils are one of the primary types of white blood cells, that evokes the immune response against any foreign particle attack in the body. Eosinophils are another type of white blood cells, that helps in fighting against disease and allergies. Basophils are such white blood cells that help to diagnose the specific health problems like autoimmune disease or other blood disorder, etc. in the body.

Answer:

xylem & phloem are present in both woody and herbaceous stems

Explanation:

Vascular system is present in both, woody and herbaceous stems. Thus, option A, and D are correct.

In vascular plants, A tissue which is complex in nature, formed by more than one type of cells are called as vascular tissues. Two main types of vascular tissues are:

The transportation of water from roots to stem and leaves of the plant is carried out by xylem. Xylem consist of tracheids and vessel elements, which have different characteristics,  but both play significant role in transportation of water and nutrients.  

The soluble organic compounds synthesized during photosynthesis in the plants are transported by another vascular tissue called as phloem, in process called translocation. It consists of sieve elements, parenchymal cells, fibers, and sclereids.

Therefore xylem and phloem are present in both, woody and herbaceous stems.
