Answer:
5. Nucleus
Explanation:
the nuclues controls all functions of the brain and also contains dna. It's like the brain of the cell. So the nucleus would be a key component in the plant's decision to become a fruit. Plus it said instructions..instructions aren't found anywhere else
B)vascular tissue and seeds
C)flowers and vascular tissue
D)enclosed seeds and flowers
Answer:
b - vascular tissue and seeds
Explanation:
A.
all the DNA strands in the two DNA molecules will have both parental and newly synthesized DNA.
B.
it results in two nonidentical DNA molecules.
C.
each of the two DNA molecules will consist of one parental strand and one newly synthesized strand.
D.
of the two DNA molecules, one is made up totally of parental DNA, while the other is entirely newly synthesized DNA.
E.
one DNA strand is replicated continuously, while the other must be replicated discontinuously.
The media are widely used in microbiology laboratories to isolate and identify specific bacterial species or groups based on their growth characteristics and metabolic activities.
Yes, a media can indeed be both selective and differential, and such media are commonly referred to as "selective-differential media" or "selective and differential media."
These types of media are designed to encourage the growth of specific microorganisms while also allowing for the differentiation of various microbial groups based on their metabolic characteristics or other properties.
Here's how they work:
1. **Selective Aspect:** Selective media contain ingredients that inhibit the growth of certain types of microorganisms while promoting the growth of others.
This selectivity is achieved through the addition of chemicals or compounds that inhibit the growth of unwanted microbes. For example, the addition of salts, dyes, or antibiotics can inhibit the growth of specific bacterial species.
2. **Differential Aspect:** Differential media contain indicators that allow for the differentiation of microorganisms based on their metabolic activities.
These indicators can be substances that react with specific metabolic byproducts produced by microorganisms, causing observable changes in the media.
For example, pH indicators can change color in response to the production of acids or alkaline compounds by different bacteria.
Common examples of selective-differential media include:
- **MacConkey Agar:** Selective for Gram-negative bacteria and differential for lactose fermenters (pink colonies) vs. non-lactose fermenters (colorless colonies).
- **Mannitol Salt Agar:** Selective for staphylococci and differential for mannitol fermenters (yellow colonies) vs. non-fermenters (pink/red colonies).
The combination of selective and differential properties allows microbiologists to efficiently screen for the presence of target organisms and gain valuable information about their biochemical capabilities.

Answer: earths ocean has more impact.
explanation:
the ocean provides a larger amount of oxygen than all the plants on earth including the amazon rainforest. freshwater isn’t as important because it doesn’t produce that much oxygen and the ocean provides more minerals and food.
B.) Starch is found in plants, and glycogen is found in animals.
C.) Starch is composed of fructose, and glycogen is composed of glucose.
D.) Starch is a monomer, and glycogen is a polymer.
The right answer is B.
Starch is, along with cellulose, the most common polysaccharide in the plant world. It constitutes the essential energy reserves of plants and is a component of the diet of humans. It is part of the group of slow sugars. Its consumption is particularly recommended to those who practice a sport.
Glycogen, which is a polysaccharide, is the form in which carbohydrates are stored in the body (animals and fungi). Glycogen is broken down into glucose molecules when the body needs energy.
The starch is an energy storage molecule found in plants whereas glycogen is the storage molecule found in the animals. Therefore, option (B.) is correct.
Further Explanation:
The carbohydrates are the biomolecules made up of carbon (C), oxygen (O), and hydrogen (H) atoms. They perform a large number of functions in the body of an organism. These include cell identification, energy storage, serving as raw material for the formation of molecules like nucleic acid, and providing support to the cell.
The simplest type of carbohydrates is monosaccharide. They join with one another by glycosidic linkage to form large carbohydrate molecules (polysaccharides) like starch, glycogen, and cellulose. Starch and glycogen act as a storage molecule. They have glucose as their monomeric unit. Glycogen is present in animals and is stored in the liver as well as skeletal muscles. However, carbohydrate is stored in the form of starch in plants. It is stored in the stroma.
