Oh boy, there's many, many, many, many...
(many x100)
many ways!

One way is to take shorter showers and conserve water wherever you go, at home, at a restaurant, hotel, etc.

Another way is to not litter on the streets.

Or, spread the word and tell everyone to conserve water, not litter, or just anything to help the environment!

<h2>Reproductive Method </h2>

Explanation:

<em>The rank in order from the most specific which is following .</em>

<em>(1) Reproductive isolating mechanism</em>

<em>(2) Sperm-egg incompatibility in sea urchins</em>

<em>(3) Gametic isolation </em>

<em>(4)Prezygotic isolating mechanism</em>

<em>(1) Reproductive isolating mechanism-</em> The components of regenerative confinement are an assortment of transformative instruments, practices and <em>physiological procedures basic for speciation.</em> They keep individuals from various species from delivering posterity, or guarantee that any posterity are sterile.

(<em>2) Sperm-egg contradiction in ocean urchins-</em> Bindin is a gamete acknowledgment protein known to control species-explicit <em>sperm-egg grip</em> and layer combination in ocean urchins.

<em> (3)Gametic isolation - Prezygotic hindrances </em>keep preparation from occurring. Gametic disengagement is a sort of prezygotic hindrance where the<em> gametes (egg and sperm) </em>come into contact, yet no preparation happens. Gametes might be not able to remember each other in various species

<em> (4) Prezygotic isolating mechanism- </em>while postzygotic segregation forestalls the arrangement of rich posterity. Prezygotic systems incorporate environment segregation, mating seasons, "mechanical" disconnection, gamete detachment and conduct seclusion.

Gwar [14]

Answer:

A. centrosome

Explanation:

The centrosome is known as the main microtubule-organizing center in the animal cells.
The centrosome constitutes of two centrioles and is surrounded by the pericentriolar material which is nothing but a structured matrix of proteins.
It is the center through which the microtubules emerge.
In animal cells, the centrosome is associated with the formation of spindle fibres.

Which of the following terms is used to describe the steady breeze of particles flowing out from the sun?

STALIN [3.7K]

<h2>Answer:</h2>

The term is <u>solar wind</u>.

<h2>Explanation:</h2>

The breezy particle which is produced from the corona region of the sun is called as Solar wind. It is made up of electrons, protons and alpha particles with kinetic energy. Implanted inside the sunlight based breeze plasma is the interplanetary attractive field.

The sun oriented breeze shifts in thickness, temperature and speed after some time as the sunlight changes. Its particles can get away from the Sun's gravity on account of their high vitality coming about because of the high temperature of the crown, which is caused due to source of origin called corona.

If all variation among individuals in a population is due to differing genotypes alone, heritability is _____, and the slope of

AVprozaik [17]

Answer:

<em>If all variation among individuals in a population is due to differing genotypes alone, heritability is 100% and the slope of the line used to measure it is 1.</em>

Explanation:

If the genes play no role in the variation among organisms of a species, then the heritability will be zero percent. Hence, if all the variations among individuals of a population occur due to the differences in the genotype, hence the heritability will be 100%. This is because genes are the hereditary molecules and the genotype of an organism comprises of the different genes present in an organism.
