What do we call large molecules that are found in living things?

Biology
1 answer:
Sliva [168]3 years ago
8 0

Answer:

basically "building blocks"

Explanation:

Living things are made up of very large molecules. These large molecules are called macromolecules because “macro” means large; they are made by smaller molecules bonding together. Our body gets these smaller molecules, the "building blocks" or monomers, of organic molecules from the food we eat.

There is evidence that Emanuel Swedenborg<span> first proposed parts of the nebular hypothesis in 1734.</span>[3][4] Immanuel Kant<span>, familiar with Swedenborg's work, developed the theory further in 1755, publishing his own </span>Universal Natural History and Theory of the Heavens, wherein he argued that gaseous clouds (nebulae<span>) slowly rotate, gradually collapse and flatten due to </span>gravity<span>, eventually forming </span>stars<span> and </span>planets.<span>[2]</span>

In garden peas a pure line that is tall with purple flowers is crossed to another pure line that is short with white flowers. Th
defon

Answer:

See the explanation

Explanation:

Answer 1.

As given that in F1 all are short and white then it can be said according to Mendel's law that short and white are dominant over tall and purple.  

Let S for short s for tall and W for white and w for purple allele.

So the genotype of short purple will be Ssww or SSww. So In first case Ssww self crossed then resultant offsprings will be,

................ Sw .................... sw

Sw ........ SSww ............. Ssww

sw ........ Ssww .............. ssww (tall and purple)

So from this 1/4 will be tall and purple while 3/4 will be short and purple.

In second case SSww only short purple progeny will appear.

Answer 2.

2. a) The female progeny will not show any trait because there are two X chromosome in females , so female offspring can be carrier but not show any trait in case of X- linked trait.

2. b) Half of male offsprings show trait because X is inherited from mother. So the chance of having X-linked recessive allele is 1/2.

2. c) The chance of having X linked affect allele in daughter is 1/2. So the chance of inheriting that X to son will be 1/2 so in total there is chance of 1/4 that son will be affected.

2. d) the chance of first child show this trait will be 1/4 in case of male offspring while 0 in case of female offspring.

Hope this helps!

Plant cells have mitochondria, which use glucose to produce ATP. Where does the glucose originate?
Romashka [77]

Plant produces glucose in the chloroplast through the process of photosynthesis. Calvin cycle is basically the biological process through which glucose is produced. The steps involved are as follows:

1. Absorbed CO2 is added to RuBP and 6C sugar is formed.

2. Breaking of 6C sugar into two  3-phosphoglycerate molecules

3. ATP gives phosphate group  to form 3-phosphoglycerate which is later on converted into 1,3-biphosphoglycerate.

4. Electons are required by 1,3-biphosphoglycerate to an aldehyde called glyceraldehyde-3-phosphate or G3P and these electrons are donated by NADPH

5. Enzyme aldolase uses two molecules of G3P to produce 6 C sugar called  fructose-1,6-biphosphate which is further converted to fructose-6-phosphate

6. Enzyme  isomerase converts fructose-6-phosphate to glucose-1-phosphate

What do you call a person who studies plants and animals?
Gekata [30.6K]
A biologist whose interest lies primarily in the study of plants or animals can be called a naturalist, although these days it's more likely she'll be called a natural historian, a botanist, or a zoologist.
