Explanation: Gametes are the cells used during sexual reproduction to produce a new individual organism or zygote. The male gamete, sperm, is a smaller, mobile cell that meets up with the much larger and less mobile female gamete, egg or ova. Both sperm and egg are only haploid cells. They only carry half of the chromosomes needed.
Answer:
The correct answer will be option-Yes--every species represents a resource that may be exploited by an array of parasites
Explanation:
Parasites are the organism which for survival depends on the resources of the host organism and utilize them to the extent that it could lead to the death of the host.
The interaction between the parasite and host proves harmful to the host but beneficial to the parasite.
A number of parasites exist for human species which can directly harm humans. Similarly, a large number of hosts exist for different species which belongs to another kingdom also like even the bacteria has a parasite called bacteriophage which utilizes the resources of the host.
This indicates that every species has some resources which can prove beneficial to another organism in the response of which they become host to a large number of parasites.
Thus, the selected option is the correct answer.
Answer:
chlorophyll is the answer
Yellow- Green Wavelength of light at peak absorption of 565nm.
Halobacterium is known to be a member of Archaea
and they thrive in very salty environment such as Great Salt lake and Dead Sea. Halobacteria under the process of photosynthesis
with chlorophyll and they make their ATP from the sunlight using bacteriorhodopsin
and halorhodopsin as photosynthetic pigments.
However, photosensory pigements found in
Halabacterium were:
1. photosystem 565 which is used to respond to yellow
–green light in other for cell to find optimum conditions for ATP synthesis and
photophosphorylation and they have peak absorbtion at 565nm.
2. Photosystem 370 nm appears to be responsible
for the protective avoidance of blue/UV light.
