Answer:
D
Explanation:
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.

❀ 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.

Si contamos con mas tecnologia ahora,por que creen que no es posible regresar de Marte si lo es regresar de la Luna
Answer:
Debido a la gravedad.
Explicación:
No es posible regresar de Marte si es posible regresar de la Luna porque la masa es un planeta que tiene una alta fuerza de atracción gravitacional en comparación con la luna que tiene una fuerza gravitacional muy baja. La luna es una estrella que tiene una fuerza gravitacional baja mientras que, por otro lado, Marte es un planeta y más grande que la luna, por lo que tiene más fuerza de atracción gravitacional en comparación con la luna y esa es la razón por la que no podemos regresar de la luna fácilmente desde el Marte en comparación con la luna.

Which factor does NOT provide evidence of common ancestry?
a.) DNA
b.) organism size
c.) stages of early development
d.) homologous structures
The size of the organism does not provide any evidence of common ancestry. So, the correct option is B.
What do you mean by Common ancestors?Common ancestors may be defined as those characteristics of different organisms that have two or more descendants in common.
The nature and morphology of the DNA, stages, and properties of the early development of organisms, and homologous structures provide significant evidence of common ancestry between the organisms of different species.
Therefore, the correct option for this question is B.

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
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 unitsCross:
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

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

According to Friedman and Roenman study, high levels of stress are linked to Coronary heart diseases (CHD). Thus, the correct option is D.
What was Friedman and Roenman theory?
Friedman and Rosenman in the year 1976 conduced a research to show that people with type A personality run a higher risk of heart disease and high blood pressure than type Bs. Type A personality is ambitious, competitive, and aggressive while type B personalities may be patient, flexible, and laid-back.
Through their study, they remarked that the primary risk factors of Coronary Heart diseases (CHD), i.e. hypertension, smoking, and elevated serum cholesterol were found at a higher level in the people with personality A than that of personality B.
