What process keeps the amounts of molecules inside and outside the cell in balance

<em>Answer: </em><em>homeostasis</em>

<em>Explanation: </em><em>Homeostasis is the ability of a system to maintain a balance in its internal environment. At the level of an organism, it is the set of parameters that must remain constant or adapt to the needs, such as blood pressure or heart rate, body temperature, blood glucose.</em>

<em />

<em>The concept of homeostasis was mentioned for the first time in 1866 by French physician and physiologist Claude Bernard. Today, the concept has been extended to other systems than purely organic ones, and can also be applied to an ecosystem</em><em>.</em>

Answer:

Diffusion

Explanation:

Diffusion is the process through which molecules in the cell are kept in balance with those outside the cell.

Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration.

Through the above mechanism, molecules having higher concentration in the cell move out of the cell and vice versa thereby maintaining the balance of molecules in and outside the cell.

Is it true that ocean biomes contain a wider biodiversity than land biomes why or why not?
EastWind [94]
The difficulty with this answer, lies in the fact that not all of land and ocean biomes have been completely explored. The ocean is vast, covering approximately 70% of the Earth's surface, with literally vertical miles or kilometers of depth, and with some areas with sparse to no biodiversity. The same can be said about certain areas of large deserts with very low levels of biodversity, void of life, like vast deserts of the Sahara or Gobi. But, the Amazon rain forest contains still unknown species of plant and animal life, just like the ocean. Because of its vastness, intellectually, I would say  the ocean contains more biodiversity, but the answer is scientifically, as of now, yet to be proven one way or the other.

The Punnett square shown presents a cross between two piranhas. Both parents have large teeth.
Llana [10]

Answer:

The correct answer would be C)  75% large-toothed and 25% small-toothed.

It can be explained with the help of the law of dominance which states that the dominant allele expresses itself completely over the recessive allele in the heterozygous condition.

So, the genotype TT, as well as Tt, will result in the production of dominant trait or character in the offspring.

Thus, three (1 TT and 2 Tt) out of four offspring would have large teeth and only one offspring (tt) would have small teeth.

Hence, we can conclude that 75% of the offspring will have large teeth and only 25% will have small teeth.

1. What evidence supports the notion that sponges are some of the earliest known multicellular animals?
Serga [27]

<u>Answer:</u> "Chemical fossils"evidence supports the notion that sponges are some of the earliest known multicellular animals.

<u>Explanation:</u>

Sponges are multicellular animals, may belong to Ediacarian period likely to be 80 million years ago or earlier. They catered through a complex system of internal channels, by moving seawater.

Sponges are soft-bodied and very rarely protected as fossils, therefore finding evidence of existence is giant task. The key of their existence came to know from abnormal chemicals which is a steroids of a particular type generated sufficiently by them but virtually never by ordinary organisms.

Analysis of long strata sequence found in Oman and researchers have been able to extract these "chemical fossils" from samples spanning tens of millions of years — before, during and after the Ediacarian period.This gave clear evidence that sponges had to have evolved long before the great variety of multicellular organisms proliferated at the dawn of that time.

What statement best describes the relationship between the products of photosynthesis and the reactants in cellular respiration
zalisa [80]

The products of photosynthesis is to gain energy and build compounds, like glucose from carbon dioxide, making it anabolic

The reactants of cellular respiration are catabolic, and that refers to the breaking down of compounds, which releases energy.

The relationship is that they're complex compounds that consist of materials coming from essential processes in the cell.
