The primary function of most of the bacteria in the food is to decompose the materials present in the environment.
The plants and animals that die in the environment is consumed by the bacteria so that the nutrients can be recycled in the soil.
These bacteria are present everywhere because all the living organism die a day.
The bacteria and fungi digests the organic part of the ecosystem. This is the primary function of the bacteria that is found in the food web.
How does comparative anatomy support the idea that organisms share ancestors?
sequence of the following star outcomes in order of the mass of the original star, with the smallest mass first: neutron star, white dwarf, and black hole?
-has a mass no greater than 1.4MSun
- typically about the size (diameter) of Earth
-usually has a very strong magnetic field
-sometimes appears as a pulsar
-size defined by its Schwarzschild radius
-viewed from afar, time stops at its event horizon,
What does the biodiversity on Earth indicate about its organisms? a)They share many common structures and functions.
b)They are adapted to live in a variety of environments.
c)They have not changed over the course of Earth’s history.
d)They cannot tolerate extreme environments.
Which of the following macro molecules consist of long chains of amino acids?
Polypeptide chains consist of long chains of amino acids. They are formed together by peptide bonds.
Red blood cells are efficient oxygen transport cells. Of the following characteristics, which is the major contributor to the significant oxygen-carrying capacity of a red blood cell?
The correct answer is - red blood cells are biconcave.
RBC or the red blood cells are the cells that play an important role by many means such as transferring nutrients, hormones, and oxygen throughout the body. The transfer of the oxygen is accompanied by the help of hemoglobin, a protein that carries oxygen and takes it to the different sites in the body.
These cells are biconcave which helps them to provide more cell surface area to grab or attain maximum space for hemoglobin which helpful in oxygen significant oxygen-carrying capacity of Red blood cells.
Thus, the correct answer - red blood cells are biconcave.
to maintain a line of pure-breeding peas , selective breeders would use a technique called __________.
ADP is like a partially charged battery because it...?
How can food water and oxygen pass from the blood vessels into the body cells?
Why do a chicken embryo and a cow embryo look very similar even though the adults do not? They are not related, but still have similar development.
They are distantly related, so their development is similar.
The embryos mutate in utero to form different structures.
The genetic makeup of the two species is similar.
-They are distantly related, so their development is similar.
-Comparative embryology is the branch of embryology that compares and contrasts embryos of different species. It is used to show how all animals are related. Many things are compared (such as whether or not the organism has a notochord or gill arches).
-Embryology proves the modern theory of evolution by the similar structures found in embryos. The greater the similarity in structure, the more closely related the species are and the more recent their common ancestor is.
