Answer:surface area to volume ratio
Cell size is limited by a cell's surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell's function is determined, in part, by its shape

Why do gram negative bacteria lose the primary stain during decolorization with ethanol?.
Answer:
Conversely, the the outer membrane of Gram negative bacteria is degraded and the thinner peptidoglycan layer of Gram negative cells is unable to retain the crystal violet-iodine complex and the color is lost. ... However, the decolorized Gram negative cells are stained red.

Answer:
The correct answer is option D, that is, brainstem.
The innermost region of the brain is known as the brainstem, which continues with the spinal cord. It is the part of the brain, which associates the cerebrum with the spinal cord. It comprises the medulla oblongata, pons, and the midbrain. The sensory and the motor neurons pass via the brainstem permitting for the transmission of signals between the spinal cord and the brain.

Identify an invasive species in your local ecosystem. Discuss how the species adapted to its native environment, including the types of adaptations and adaptive techniques.
Answer:
i live near the Gulf of Mexico so the loin fish would be considered an invasive species but you can go.ogle invasive species in the state that u are in and a lot would pull up to tell u
Explanation:
Invasive species when introduced compete with the native species present in the environment for food and space. One such example of invasive species is Invasive carp.
What is adaptation?Adaptations are the changes in an organism which help them in adjusting more in an ecosystem. Adaptations can be of different types such as structural, physiological, etc depending upon the environment.
When a highly invasive species is introduced, they are more likely to compete with the native species present in the environment. When the population sizes and genetic diversity of native species are large enough, the native species may be able to evolve traits which allow them to co-occur with the invasive species and live in the same ecosystem.
One examples of invasive species is the Invasive carp, which are fast-growing, aggressive, and adaptable fishes that outcompetes the native fish species present in the waterbody for food and habitat in much of the mid-section of the United States.

Which statement accurately describes the relationship between cytokinesis and mitosis? Mitosis includes interphase and cytokinesis. Cytokinesis precedes mitosis in the cell cycle. Cytokinesis is not a phase of mitosis, but occurs during mitosis. Interphase includes cytokinesis and mitosis.
Mitosis is a type of cell division that produces two alike daughter cells. Cytokinesis is not a phase of mitosis but happens during mitosis.
What are cytokinesis and mitosis?Mitosis is a cell division type that divides the parent cell and the genetic material into two alike daughter cells with the same chromosome numbers.
Cytokinesis is a process by which at the end of the telophase the cytoplasm of the cell starts dividing and results in the formation of the plate in plants and furrows in the animal, dividing the cell equally.
Therefore, option c. Cytokinesis is not a phase of mitosis but occurs during mitosis.

Which element is essential to making up all organic molecules?.
Answer:
This element is carbon.
Explanation:
You might be quick to think the answer is something like hydrogen and oxygen because both form to make water. But understand that the question is not asking about important elements in life, just which element makes up organic molecules. This element happens to be carbon.
It's important to understand that carbon is lucky in that it has 4 valence electrons and is able to bond with other important elements, like F, N, and especially H. The bond between C-H is essential in organic chemistry because it represents the structure of an organic molecule and helps with the IUPAC naming of organic molecules. It also suffices to say that there is a cycle for carbon in the carbon cycle, which transports carbon from one place in our world to the other.
So, it suffices to say that carbon is in fact essential for making up organic molecules.

The insertion of the human insulin gene into the bacterium Escherichia coli allowed it to produce human insulin. Which type of organism is E. Coli? restriction organism recombinant organism transgenic organism vector organism.
Genetically modified and engineered organisms are that can produce the gene and the product of interest when modified. Escherichia coli is a transgenic organism.
What is a transgenic organism?
A modified organism through the genetic and molecular pathway alteration is called a transgenic organism. Various techniques are employed to alter the genetic mechanism of the organism.
They are prepared by inserting a genetic fragment of interest from some other species by the method of recombination technology and genetic engineering.
The organism in which the insertion and the alteration are done to produce the product of interest are transgenic. Here E.coli get altered by the insertion of the human insulin-producing gene.
Therefore, option C. transgenic organism is correct.

The binding of oxygen to hemoglobin differs from the oxygen binding behavior of myoglobin because
The binding of oxygen to hemoglobin differs from the oxygen binding behaviour of myoglobin because oxygen binding to hemoglobin is cooperative.
Hemoglobin - oxygen bindingHemoglobin is the oxygen carrying protein of the blood that is located at the red blood cells. They have high affinity for oxygen.
Myoglobin is found in the muscle cells and they are contain haem proteins which they used to transport and store oxygen in the muscles.
Hemoglobin and myoglobin are two types of globin proteins that serve as oxygen-binding proteins, but binding of oxygen to hemoglobin differs from the oxygen binding behaviour of myoglobin.
This is because binding of oxygen by hemoglobin is cooperative. This means that as hemoglobin binds successive oxygens, the oxygen affinity of the subunits increases. This is opposite for myoglobin.

2. A car traveled at a velocity of 50 km/h,N for .5 h. How far did the car travel?
Thank you I need it now 2/21/22
Science
Answer:
1: 6hr 2: 25km
Explanation:
The equation velocity=distance/time (v=d/t) is useful for these problems.
1: v=100 km/hr, d=600km
plugging into the equation, we get 100km/hr=600km/t
rearrange to get t=600/100, or t=6hr
2: v=50km/hr, t=5hr
plugging in: 50km/hr=d/0.5hr
rearrange: d=(50km/hr)*0.5hr, or d=25km
