echidnas hatch from an egg and delicious as they mature m. Why do the echidnas have bristles with different thicknesses?

Answers

Answer 1
They have different versions of the gene for bristle thickness that connect together to make the bristle thickness in general.

It’s like when you have 6 toothpicks and combine two together, you’ll have 1 really thick one and the others will be small.

Which two inferences about the chipmunk population can be supported with the data gathered by the biologist?

Answers

Answer:

The amount of food in the area decreased, causing more chipmunks to

survive to reproductive age.

Explanation:

Hope this helps :)

Chipmunks in later generations showed greater genetic diversity than previous generations, allowing for a greater survival rate in later generations. Individual chipmunks changed their genetic makeup and became more successful in the environment. The correct options are R and S.

What is genetic diversity?

Genetic diversity refers to the total number of genetic traits that make up a species' genetic composition.

It varies greatly depending on the number of species present as well as across species, and it can be linked to a species' longevity.

DNA contains all the biological information and variety required to sustain life on our planet.

Genetic variety is referred to as this. It improves a species' and population's resistance to maladies, pests, climatic changes, and other pressures.

According to the findings, Chipmunks had a higher genetic variety in later generations than in earlier generations, which allowed for a higher survival rate in later generations. Individual chipmunks altered their genetic make-up and improved their chances of survival.

Thus, the correct options are R and S.

How does ADH work to balance water in the bloodstream and urine??

Answers

Answer:

What does the phrase "water loss control" mean?
Read the excerpt from "Water Efficiency Strategies."
Water Loss Control—National studies indicate that, on
average, 14 percent of the water treated by water systems is lost
to leaks. Some water systems have reported water losses
exceeding 60 percent. Accounting for water and minimizing
water loss are critical functions for any water utility that wants to
be sustainable
o preventing water from being wasted due to leaks
O limiting the number of household sinks and toilets
O limiting use of dishwashers and washing machines
O preventing pipes from rusting and growing mold

Answers

Answer: Answer: preventing water from being wasted due to leaks

Explanation:

Water loss control has to do with the efforts which involves managing leakage to low levels.

From the excerpt, we can infer from the information given that 14 percent of the water treated by water systems is lost due to leaks. Therefore, the phrase "water loss control" simply means how water loss will be minimize.

The phrase "water loss control" means preventing water from being wasted due to leaks.

What is Water loss control ?

A water loss control program helps to identify real or physical losses of water from the water system and. apparent losses, the water that is consumed but not accounted for.

Water loss control includes

utility efforts to manage leakage to economically low levels, andreducing metering and billing errors such that reliable measures of customer consumption are attained and sufficient revenue is garnered by the water utility.

Three human disordersfragile X syndrome, myotonic dystrophy, and Huntington's diseaseare conceptually linked by a common mode of molecular upset. Choose the phenomenon that links these disorders.

All three are caused by disparate genes, but each gene was found to contain repeats of a unique trinucleotide sequence. All three are X-linked, but each gene was found to contain repeats of a unique trinucleotide sequence.

Answers

Answer:

The correct answer is ''All three are caused by disparate genes, but each gene was found to contain repeats of a unique trinucleotide sequence.''

Explanation:

Four groups of trinucleotide repeats related to DNA expansion have been characterized in the human genome. CGGI GCC, CAGIGTC, CTGIGAC and recently GW CTT sequences. The CGGl GCC sequences are usually located in the noncoding regions of different genes and when expanded they associate with fragile sites on the chromosomes. The CAGIGTC repeats are part of the coding region and are related to different neurodegenerative disorders. You can try to make a classification depending on the unit that is repeated, having on one side a group that are caused by repeats of the CAG trinucleotide (cytosine, adenine, guanine). Huntington's disease (HD) is a progressive disorder of motor, cognitive and psychic function. The disease is inherited in an autosomal dominant manner, and is caused by the expansion of CAG trinucleotide repeats in exon 1 of the gene called huntingtin (HTT or IT-15). Unstable mutations have also been found in which the repeat unit does not is composed of three nucleotides, if not four, such as type 2 myotonic dystrophy, where the tetranucleotide CCTG repeats. Fragile X Syndrome consists of an abnormal expansion of the cytosine-guanine-guanine trinucleotide (CGG) in the FMR1 gene, which prevents intellectual disability and also influences the formation of connective tissue

Why humans need organs, like the liver and pancreas, but amoebas do not.

Answers

Answer:

They have no use for it, just like they dont have any type of respiratory organs like lungs.

Explanation:

In the case of nutrition and digestion they obtain food by capturing their prey with their pseudopodia. The food is internalized through a type of endocytosis known as phagocytosis. Nutrients are obtained as the enzymes digest the food inside the vacuole and when they are finished the food vacuole dissolves.

Humans need organs, like the liver and pancreas, but amoebas do not because human is a complex multicellular organism that necessarily requires a variety of organs in order to perform specific functions.

What do you mean by Organs?

Organs may be characterized as collections of tissues as a part of the body that performs a specific function. Some examples of organs may include the heart, the lungs, the kidneys, the stomach, etc.

Amoeba being unicellular organism has the capability to change their shape. They capture their food through pseudopodia and diffuse the substance easily through their single cells.

While on contrary, humans are more complex living organisms on this earth planet. So, they require a specific set of organs and organ systems in order to facilitate their survival.
