Answer:

called ribosomes

Explanation:

gladu [14]2 years ago

Explanation:

Both animal and plant cells have ribosomes. Ribosomes that are attached to the endoplasmic reticulum of cells make proteins that are for secretion out of the cells while ribosomes that lie freely in the cytoplasm of the cell make proteins that are used by the cell itself. Furthermore, what type of cell are ribosomes found in?

Plants make their own food and are called producers. What do plants need to make their own food? A) soil, air and water B) soil,
djyliett [7]

Answer:

D) energy from the sun, air, and water

Explanation:

Plants are producers because they undergo photosynthesis. Photosynthesis is the process of taking sunlight, CO2, and water to produce ATP in the form of glucose and oxygen.

For plants to make their own food they require the reactants of photosynthesis. The reactants are sunlight+6CO_2 + 6H_2O. In other words, sunlight, carbon dioxide (air), and water. Without these reactants, photosynthesis cannot occur.

Things such as soil and fertilizer are helpful to a plant's growth; however, they are not required in the process that creates food for plants.

The interaction between DNA and histone proteins (forming nucleosomes) plays a key role in the regulation of gene expression in
ladessa [460]

Answer:

A. The chromatin near cis-regulatory sequences will be more closed and there will be less transcription.

Explanation:

In the presence of histones, the cis-regulatory sequences of DNA like promoter, enhancers etc. are not exposed. The function of the histone acetyltransferases (HATS) is to cause chromosome decondensation i.e. removal of histones from the DNA so that transcription of the DNA could occur. Histone acetyltransferases (HATS) cause acetylation of lysine amino acid of the histone proteins. Acetyl group is negatively charged so the acetylation of histone proteins leads to the removal of their positive charge which ultimately leads to the decrease in the interaction between N terminal of histones and negatively charged phosphate group of the DNA molecule. As soon as histones are removed from the DNA where cis-regulatory sequences are located, the DNA becomes accessible for transcription.

But here a drug has been added which blocks the activity of histone acetyltransferases (HATS) in cancer cells. So it is quite evident that in these cells, histones will not get removed from the cis-regulatory sequences of DNA so the DNA will be more closer or tightly packed as a result of which  less transcription will occur.

Pea plant clones are given different amounts of water for a three week period.
pentagon [3]

Answer:

independent variable: the different amount of water

Explanation:

The independent variable would be the <u>different amount of water supplied to the pea plant clones.</u>

<em>The independent variable is the variable inputted by the researcher during an experiment whose value directly affects the dependent variable. It is the variable that is manipulated during experiments in order to see the kind of effects they produce on another variable - the dependent variable.</em>

In this case, <u>the amount of water supplied to each pea plant would directly affect the height of the pea plants.</u> Hence, the amount of water supplied to the pea plants is the independent variable while the height of the plants is the dependent variable.

Sickle cell anemia and albinism are both recessive traits in humans. Imagine that a couple, already pregnant with fraternal twin
lidiya [134]

Answer:

81/256

Explanation:

By doing a test cross of albinism and sickle cell anemia you'll see that the probability that one child is unaffected by either conditions will be 9/16. Both children would be 9/16 * 9/16.  

Since fraternal twins are developed from two separate fertilization events the probability chance will be independent.
