Where in the cell are chromosomes located?

Correct Answer: Decomposers are those organisms that recycle matter in the ecosystem..

Explanation:

Decomposers are organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition.

 

The statement "Decomposers are those organisms that recycle matter in the ecosystem" describes decomposers.

Correct Answer: Tuber

Explanation:

Tuber is considered as a modified stem. These type of stems carry out special functions that are important for the plant to survive. Tubers serves as a food reserve and bearing buds wherein new plants can grow.

Correct Answer: Intracellular transport

Explanation:

A cytoskeleton is the frame that gives shape to a cell. And also it offers support, and facilitates movement through three main components:

microfilaments,

intermediate filaments, and

microtubules.

 

The cytoskeleton helps the cell move in its environment and controls the movement of all of the cell's interior workings.

Correct Answer: An organelle called Eyespot allows some protists to detect light It allows the cells to sense light direction and intensity and respond to it by swimming either towards the light (positive phototaxis) or away from the light (negative phototaxis) Eyespot is a photoreceptive organelle found in the flagellate or (motile) cells of green algae and other unicellular photosynthetic organisms such as euglenids Eyespot-mediated light perception helps the cells in finding an environment with optimal light conditions for photosynthesis Eyespots are the simplest and most common "eyes" found in nature, composed of photoreceptors and areas of bright orange-red pigment granules

Correct Answer: Some inherited genetic mutations can be good for the offspring.

Explanation:

Mutations are accidents in the copying of DNA. A genetic mutation is a random change in the DNA that is passed on further generations of cells and or organisms. 

 

Genetic mutations are accidental changes in the DNA in the germ cells or early in the formation of the embryo. These changes if they are in the germ cell will be passed on to other organisms formed by sexual reproduction or asexual reproduction. An example would be the golden delicious apple. A lost of genetic information due to a mutation resulted in a different color of fruit.

 

Genetic mutations that cause diseases are not always passed on to offspring. 

Correct Answer: DNA

Explanation:

The inherited traits of an organism are controlled by DNA molecules.

 

The traits an organism displays are ultimately determined by the genes it inherited from its parents, in other words by its genotype. Animals have two copies of all their chromosomes, one from each parent.

 

Correct Answer: blood

Explanation:

In human body, glucose is stored in blood stream before it is converted to glycogen. Excess glucose is stored in the form of fats. After conversion, glycogen is stored in Muscles and Liver.

Correct Answer: All the above

Explanation:

Random mutations are the ultimate source of genetic variation. Mutations are likely to be rare and most mutations are neutral or deleterious, but in some instances, the new alleles can be favored by natural selection. Polyploidy is an example of chromosomal mutation.

 

Mutations are changes in the DNA. A single mutation can have a large effect.

1) mutation - an alteration in DNA sequence, various types

2) intragenic recombination - results in entirely new associations of genes not present in either parental genome.

Two forms of intragenic recombination:

a) crossing over
b) independent assortment
3) reticulation ? acquisition of genetic material from unrelated or relatively unrelated sources (e.g., hybrid species, horizontal gene transfer).

Correct Answer: Bacteria take DNA from their environment.

Explanation:

"Bacteria take DNA from their environment" is what best describes transformation in bacteria.

Correct Answer: Aldosterone increases sodium reabsorption by increasing the number of Na+-K+ ATPase pumps in the luminal membrane of the proximal tubule.

Explanation:

Aldosterone, the main mineralocorticoid hormone, is a steroid hormone produced by the zona glomerulosa of the adrenal cortex in the adrenal gland. It is essential for sodium conservation in the kidney, salivary glands, sweat glands and colon.
