You learned in the reading that some symbiotic relationships are helpful and some are harmful. Look at the symbiotic relationships listed below and select all where at least one organism is harmed (the reading calls these harmful relationships). Group of answer choices Commensalism Parasitism Mutualism Predator-Prey Competition

Answers

Answer: Parasitism, Predator-Prey, Competition

Explanation:

The symbiotic relationship is the relationship in which two distinct species are associated with each other. In the symbiotic relation the species may get harm or benefit of association. Parasitism can be defined as the symbiotic relationship in which one species get harmed and other one receives the benefit. For example, malarial parasite plasmodium derives the nourishment from the host body (human). Predator-prey relationship is also harmful as the predator kills the prey to obtain it as food. Competition is harmful in the sense two or more organisms of the same or different species compete for the same resource, the most dominant receives the resource the inferior organism is either killed or harmed in the fight for resources.

Lack of which factor would be most likely to turn an alien species into an invasive species?


mates

suitable food

suitable habitat

predators

Answers

Answer:

predators

Explanation:

The correct answer is predators. An alien species that finds plenty of food and suitable habitat in its new home is usually able to find mates and reproduce well. But the competing species may become endangered or even extinct, because the alien (now invasive) species has no natural predators in the new environment, and its population can therefore grow without limits.

if you had to choose between the phrase "natural selection gives organisms what they need" vs. "natural selection chooses traits that are most successful", which one would you choose? defend your answer.

Answers

Answer:

Natural selection gives organisms what they need

Explanation:

The species constantly evolve because of the changes around them. Natural selection gives organisms what they NEED in order to survive. "Natural selection produces organisms perfectly suited to their environments".

Species that continually evolve because of changes around them where natural selection gives organisms what they need to survive. "Natural selection makes organisms perfectly adapted to their environment".

What is Natural Selection?

Natural selection is defined as the differential survival and reproduction of individuals due to differences in phenotype which is a major mechanism of evolution, a change in the genetic properties of populations over generations.

It is the process through which populations of living organisms adapt and change where individuals in a population are inherently variable, meaning they all differ in some way. This variation means that some individuals have better adaptations to the environment than others.

Thus, species that continually evolve because of changes around them where natural selection gives organisms what they need to survive. "Natural selection makes organisms perfectly adapted to their environment".

Which macromolecule is needed for lactic acid formation and alcohol fermentation to proceed with their processes?


IN YOUR OWN WORDS
DONT COPY FROM THE INTERNET

Answers

Answer:

sugar

Explanation:

sugar is the required macromolecule

In the lactic acid formation, pyruvate changes to the lactose which is the anaerobic form of respiration. Pyruvate changes to alcohol and carbon dioxide.

What is the main ingredient for lactic acid fermentation ?

It is the sugar molecule that is needed for the lactic acid fermentation.

Both the  types of  the fermentation requires two primary components which are a sugar supply and  bacterial culture where alcohol fermentation uses the  forms of  the yeast where the lactic acid fermentation usually depends on  the lactic acid bacteria.

Lactic acid fermentation takes place in some of the  strains of  the bacteria and in  the even skeletal muscle and even  produces lactic acid . Alcoholic fermentation takes place in the  yeast and just  produces ethanol with carbon dioxide.

Lactic acid bacteria is a type of gram-+ve bacteria which use carbohydrates as only and main carbon source. Later on lactic acid bacteria is generally cocci or rods usually have the  strong tolerance to low pH.

Answers

Answer:

1. Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination. 2. DNA polymerase 3. Before mRNA leaves the nucleus of a eukaryotic cell, a cap is added to one end of the molecule, a poly A tail is added to the other end, introns are removed, and exons are spliced together. Sequence of nucleotides in messenger RNA is translated into a sequence of amino acids. 4. In RNA splicing, specific parts of the pre-mRNA, called introns are recognized and removed by a protein-and-RNA complex called the spliceosome.

Explanation:

I hope this helps. ^_^

Transcription starts off evolving while RNA polymerase binds to a promoter series close to the start of a gene (without delay or via helper proteins). RNA polymerase makes use of one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription leads to a process known as termination. DNA polymerase enzyme copies the DNA.Before mRNA leaves the nucleus of a eukaryotic molecular, a cap is introduced to at least one quit of the molecule, a poly-A tail is introduced to the opposite quit, introns are eliminated, and exons have spliced together Sequence of nucleotides in messenger RNA is translated into a series of amino acids. In RNA splicing, unique elements of the pre-mRNA, known as introns are identified and eliminated via way of means of a protein-and-RNA complicated known as the spliceosome.

What is DNA  Transcription?

Transcription is the technique of creating an RNA replica of a gene series. This replica, known as a messenger RNA (mRNA) molecule, leaves the molecular nucleus and enters the cytoplasm, wherein it directs the synthesis of the protein, which it encodes.

The ability to curl the tongue in dominant to the inability to do so. If Eric (heterozygous tongue curler) marries Brandy (also heterozygous) what are the predicted GTs and PTs of the offspring?

Answers

Answer:

Genotype = 1CC: 2Cc: 1cc

Phenotype = 3 tongue curler : 1 non-tongue curler

Explanation:

This question involves a single gene that codes for the ability or not to curl the tongue. The ability to curl the tongue (C) is dominant to the inability to do so (c). This means that a heterozygote will be able to curl his/her tongue.

According to this question, If Eric, who is a heterozygous tongue curler (Cc) marries Brandy who is also heterozygous (Cc) i.e. Cc × Cc, the following gametes will be produced by each parent: C and c.

Using these gametes in a punnet square (see attached image), the predicted genotype of the offspring is 1CC: 2Cc: 1cc while the predicted phenotype is 3 tongue curler : 1 non-tongue curler.

A cat's coloring is mostly determined by genes on their X chromosomes, which contain alleles for colors, such as black, orange, gray, and cream. The allele for white fur is located on a different gene. Calico cats, by definition, must display three different colors in their fur - white plus two of the other colors. This is easily possible in female cats, because females normally possess two X chromosomes. However, this occurs rarely in male cats, because males typically possess only one X chromosome plus one Y chromosome. What must be the genetic make-up of a male calico cat, and what type of chromosome disorder does this most resemble?

Answers

Answer:

XXY, Klinefelter's syndrome

Explanation:

In humans, as well as in many mammals, biological sex is determined by a pair of sex chromosomes (X and Y) which combine to produce a female phenotype (XX) or a male phenotype (XY). In humans, the Klinefelter syndrome (KS) is a chromosomal disorder resulting from two or more X chromosomes in males. In cats, there are documented rare cases in which male cats can also inherit two X chromosomes in addition to the Y chromosome, so they are XXY instead of XY (similar to the Klinefelter syndrome in man). Also in cats, the calico-colored is a phenotype result from the inactivation of one X chromosome, which usually occurs in cat females. However, approximately one in every 3,000 male cats have the XXY condition, and these male cats may also exhibit a “calico” phenotype.
