Eccrine sweat gland s differ from sebaceous glands

1 answer:

7 0

Eccrine sweat glands are different from sebaceous sweat glands, because eccrine sweat glands are localized to the dermis and upper region of the hyodermis.The perspiration out of these glands is mostly water, however there are also traces of salt and electrolytes. Their main job is to regulate body temperature. However, the sweat can also be from a different stresser (ex. emotional or psychological). Now, sebacous galnds differ because they do not secrete sweat. They secrete an oily substance that is known as sebum. The sebum lubriactes and protects skin, hair, and nails. Most sebaceous galnds are connected to a hair follicle, but some can also be found in the skin and they directly open to the skins surface. Both glands work together at times to regulate body temperature. In really hot conditions, the sebum will mix with the sweat to slow the evaporation rate so the body can stay cool longer.

1. Why does mitosis/asexual reproduction occur in all organisms??

arlik [135]

Answer:

Mitosis occurs in all organism and is very important for them. In multicellular organisms,Mitosis allows the growth of cells, regeneration of organs and repairing of worn out cells. In asexually reproducing organisms mitosis is the process of reproduction. In unicellular organisms mitosis helps to produce identical copies.
Some examples of Different types of asexual reproduction are as follows:

a) Fission- seen in Amoeba, Paramecium etc.

b) Budding- seen in Hydra, Yeast etc.

c) Fragmentation- seen in Microstomum

d) Zoospore - Motile asexual spores formed Ectocarpus, Ulothrix etc.

e) Vegetative propagation- Seen in plants that grow from parts other than seed.

3. Advantages of asexual reproduction:

i)No need of sexual partners.

ii) Genetic vigour of parent is preserved . Individuals are identical copies of parent.

iii) Rapid rate of reproduction.

4. Some Disadvantages of asexual reproduction:

i) No chance of obtaining new combination.

ii) Rapid reproduction leads to overcrowding and increased struggle for existence

5. The type of reproduction that involves the fusion of two gametes from different individuals is called sexual reproduction.

6. A gene has alternating forms, these forms are called alleles.

7. Sexual reproduction has greater variation because it involves recombination of traits from two parents.

8. All species do not have same chromosomes. Chromosome number is fixed for a particular species e.g. Humans have 46 chromosomes., Onion has 16 chromosome etc.

9. Human haploid cell contains 23 chromosomes.

10. Fusion of a haploid male and a female gamete to form a diploid cell called zygote is called fertilisation.

11. The first diploid cell that is formed after fertilization which can develop into a new organism is called zygote.

12. Diploid number is represented as 2n

Haploid number is represented as n.
