A. The DNA in the nucleus would be protected from harmful substances

B. Enzymes would not be able to speed up reactions in the nucleus.

C. The nucleus would not be able to communicate with the rest of the cell.

D. Large molecules would be able to enter and damage the nucleus.​

Answers

Answer 1

Answer:

D

Explanation:

Answer 2

If the layer of nucleus were permeable to most substance, then the large molecules would be able to enter and damage the nucleus.

What is nucleus?It is a membrane-bound organelle present in the centre of cell in which thread like structures called chromatins are present which condenses to form chromosomes contains genetic material (that carries genetic information from parents to offspring).It controls all function of the cell.The layer or membrane around nucleus is called nuclear membrane is semi-permeable in nature which means that only specific molecules and ions can move across it.If the membrane would become permeable, then movement of all types of molecules will occur which will disturb the homeostasis (maintaining balance) of cell and can damage the nucleus.

Hence, the correct option is: D. Large molecules would be able to enter and damage the nucleus.

Use the following information to answer the questions below. Skin color in a certain species of fish is inherited via a single gene with four different alleles. One fish of this type has alleles 1 and 3 (S1S3) and its mate has alleles 2 and 4 (S2S4). If each allele confers a unit of color darkness such that S1 has one unit, S2 has two units, and so on, then what proportion of their offspring would be expected to have five units of color

Answers

Answer:

1/2 = 50% of the progeny is expected to have 5 units of color → S1S4 + S2S3

Explanation:

Available data:

Single gene with four different alleles → S1, S2, S3, S4Each allele confers a unit of color darknessS1 one unitS2 two unitsS3 three unitsS4 four units

Cross:

Parentals) S1S3    x    S2S4

Gametes) S1   S3     S2    S4

F1) 1/4 = 25% of the progeny is expected to be S1S2 → 3 units

    1/4 = 25% of the progeny is expected to be S1S4 → 5 units

     1/4 = 25% of the progeny is expected to be S2S3 → 5 units

     1/4 = 25% of the progeny is expected to be S3S4 → 7 units

1/2 = 50% of the progeny is expected to have 5 units of color → 1/4 = 25% S1S4 + 1/4 = 25% S2S3

the process that plants go through to capture and use energy from the sun to make food (glucose ) is called Photosynthesis

..................................................More:-

Photosynthesis is a process by which phototrophs convert light energy into chemical energy.

The word “photosynthesis” is derîved from the Greek words "phos" (which means “light”) and "σύνθ-εóîς" (which means “combining together.”) And so it means “combining together with the help of light.”

The process of photosynthesis occurs in green plants (the primary producers in a food chain) and a few other autotrophic organisms such as cyanobacteria, purple bacteria and green sulfur bacteria.

Following is the photosynthesis formula:

︎︎︎ 6 CO2 + 6 H2O —> C6 H12 O6 ([tex]\sf\blue{glucose}[/tex]) + 6 O2 ([tex]\sf\pink{oxygen}[/tex]).

Mold is made up of many fungi cells. Mold would be considered what type of organism?
A. unicellular

B. prokaryotic

C. multicellular

Answers

Answer:

The answer is Multicellular

Mold would be considered a multicellular organism, which is made up of many fungi cells.

When it is said that living beings are made up of cells, what is meant is, if they are multicellular organisms.

Eukaryotes include all members of the animal and plant kingdoms, including fungi, which exist both in multicellular forms (molds) and in unicellular forms (yeasts), and protozoa, which are exclusively single-celled.

About multicellular organism molds:

The filaments that make up the mycelium are called hyphae.

The hyphae may be separated into generally multinucleated sections by means of perforated septa, or may be absent.

The cell wall of the mycelium of molds resembles an extensive tubular system through which the cytoplasm advances to disperse and search for nutrients.

Therefore, we can conclude that mold would be considered a multicellular organism, which is made up of many fungi cells.
