how many organelles are there in a cell. What are their names and what do they do. I am keeping notes

Answers

Answer 1

Answer:

Nucleus - controls all activities of the cell

Nucleolus (in the middle of the nucleus)

- the synthesis of ribosomes and RNA (ribonucleic acid)

Mitochondria (battery of cell) - oxidise glucose to release energy in the form of ATP ( adenosine triphosphate)

Edoplasmic reticulum

1. Smooth - synthesises lipids

2. Rough- Transport proteins synthesised by ribosomes

Golgi apparatus ( golgi body, or any golgi, is has many names)

- Acts as Centre for processing, packaging and transporting macromolecules such as proteins and carbohydratez

Ribosomes - sites of protein synthesis

Lysosomes- Break down macromolecules such as proteins, lipids etc

Vacuoles - store food substances, site for waste products

Centrioles - form spindle fibres during cell division

Cytoplasm ( the so call empty spaces in the cell)

- place where biochemical reactions occur

Plasma membrane

-control movement of substances in and out of the cell due to its semi permeable characteristics

Ok that's all for animal cells, but for plants cells, there is more

Cloroplast - site for photosynthesis

Cell wall - Maintains the shape of plant call, give support to cells

Is this a good problem/observation?

Answers

Yes, but maybe limit your experiment to a certain type of plant. Because you’re changing the type of plant and the frequency it may interfere. So maybe put only one specific type of plant- so maybe say something like “I want to observe whether my wild flowers grow faster depending on the frequency I water them- once a day in comparison to once every two days, or a week.”

Which of the following statements about eukaryotic RNA is true?
O -A small cap of extra nucleotides is added to both ends of the RNA.
O -The modified RNA molecule is transported into the nucleus.

-Exons are spliced together.

-Introns are not transcribed from DNA to RNA.

Answers

Answer:

A small cap of extra nucleotides is added to both ends of the RNA

Hope you like it

Thank you ❤️

The statement 'exons are spliced together' is TRUE. The exons are the coding regions of genes.

RNA splicing is a eukaryotic mechanism by which non-coding sequences of genes called 'introns' are removed from the precursor messenger RNA (pre-mRNA), whereas protein-coding sequences called 'exons' are spliced together.

These gene coding sequences (exons) are spliced together by a macromolecular complex known as the spliceosome.

In consequence, a pre-mRNA is converted into a mature mRNA, which is subsequently used for protein synthesis.

In conclusion, the statement 'exons are spliced together' is TRUE.

A hypothesis is a crucial part of the scientific method. It is a testable explanation of an observation or a proposed answer to a scientific question.

A hypothesis, which must be testable via experimentation, can either be accepted or rejected depending on the outcome of the experiment.

A hypothesis is an IF, THEN statement that must include the independent and dependent variables of the experiment i.e. it must show how the dependent variable (effect) is affected by the independent variable (cause).

Answers

Answer: the answer would be a

Explanation: because I had the same question too on acellus and got a right

Photosynthesis makes use of light energy while chemosynthesis is the main source of energy capture where light energy is not available.

What is photosynthesis?

It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy  through the process of cellular respiration.

Some of the energy which is converted  is stored in molecules of carbohydrates like sugar and starches  which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis  are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.

The process begins with proteins absorbing light energy  which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

Answers

The biopsychosocial approach is most directly concerned with assessing the relative contributions of heredity and experience to personality development (Option C)

The Biopsychosocial Approach is an interdisciplinary model which was first developed by George Engel and Jon Romano (1977).

The biopsychosocial approach is a type of model that recognizes biological (inheritance), psychological, and social (environmental) factors as well as the interactions among these factors to understand the health and illness state of an individual.

Social factors include economical, environmental, and cultural factors (e.g. work concerns and family issues).

Biological factors include both genetic and biochemical factors.

According to this approach, both mind and body determine the health of the subject.

When glycogen is formed from monosaccharides, it occurs by a process called hydrolysis.

True

False

Answers

Answer:

yes its true. it occurs by a process called hydrolysis

The formation of glycogen from monosaccharides happens through the process of dehydration. So the statement is false.

What is the process of glycogen formation?

The process of formation of glycogen is called glycogenesis. Glycogen is the storage form of glucose, a primary carbohydrate in the liver and the muscle cells of animals

The process of Glycogenesis happens when the levels of glucose in the blood are high enough to allow the excess glucose to be stored.

The process of glycogenesis is stimulated by the insulin hormone. It helps the muscle cells to uptake glucose into themselves. Insulin is not required for the transport of glucose into the liver cells.

However, insulin has very important effects on the metabolism of glucose inside the liver cells. Insulates stimulates the process of glycogenesis and inhibit the process of glycogenolysis, which is the breakdown of glycogen into glucose.

Therefore the statement is false.
