Answer:
<h3>
Constant movement around the sun</h3>
Explanation:
We have different seasons because of the earth’s constant movement around the sun. The closer a place on earth is to the sun, the warmer it will be. The farther away it is, the colder it will be.
<h3>Brainiest?</h3>
Answer:
0%
Explanation:
This involves a single gene coding for melanin pigment in the skin. The recessive form of this gene (allele) is albinism while the dominant form is a normal skin. The question highlights that the normal male parent (dominant) has no family history of albinism, this means that nobody in their family has ever possessed albinism or has been a carrier/heterozygous for the trait. This is because a carrier/heterozygote will always produce the recessive trait (albinism) if crossed with another carrier or albino individual.
In a nutshell, the normal male parent is homozygous for the dominant trait. Hence, if a homozygous dominant male is crossed with an albino woman (homozygous recessive), all their offsprings will possess a heterozygous genotype and dominant phenotype. Meaning that none of their children will ba an albino.
Hence, the percentage of their child being an albino is 0.
Answer:
Option-B, C and E
Explanation:
Archaebacteria are a group of prokaryotes which can survive the extreme conditions. The archaebacteria which can survive very high temperature are called hyperthermophiles. The hyperthermophilic bacteria can survive temperature range between 70 t 125 °C observed in hydrothermal vents.
The archaea bacteria can withstand the high temperature as their membrane is adaptive. The membrane of the archaea is more stable due to the ether linkage which makes carbon less chemically reactive. The phospholipids possess a monolayer which decreases the layer fluidity and thus the unwanted movement of molecules.
The archaea also contain cyclopentane rings in the ester-linked phospholipids which allows tight pacing of the molecules which decrease the movement of solute into and out of the cell.
Thus, the selected options are correct.
True. Sensory cells are are cells responsible for detecting information through receptors that are found on the surface of the body. Information like sound, touch, taste, smell, and even temperature are detected through several sensory cells in the body. The skin, nose, tongue, and ears are organs of the body that are composed of several of these cells.
Answer:
Mammals give live birth to their offspring. Reptiles and amphibians lay eggs. Mammals are also usually warm blooded while reptiles and amphibians are cold blooded. Most amphibians and reptiles abandon their young at a certain age while most mammals will take care of their offspring forever.
