Answer:
Explanation:
Invasive species are among the leading threats to native wildlife. Approximately 42 percent of threatened or endangered species are at risk due to invasive species.
Human health and economies are also at risk from invasive species. The impacts of invasive species on our natural ecosystems and economy cost billions of dollars each year. Many of our commercial, agricultural, and recreational activities depend on healthy native ecosystems.
What Makes a Species "Invasive"?
An invasive species can be any kind of living organism—an amphibian (like the cane toad), plant, insect, fish, fungus, bacteria, or even an organism’s seeds or eggs—that is not native to an ecosystem and causes harm. They can harm the environment, the economy, or even human health. Species that grow and reproduce quickly, and spread aggressively, with potential to cause harm, are given the label “invasive.”
An invasive species does not have to come from another country. For example, lake trout are native to the Great Lakes, but are considered to be an invasive species in Yellowstone Lake in Wyoming because they compete with native cutthroat trout for habitat.

I observed that after I used the detergent in my experiment, the average droplets I was able to get on the penny decreased drastically. My results seemed to be better before when I was just using the water. This is an example of Capillary action.
why does water have partial negative and positive charges?
Explanation:
Water is H20 which is 2 hydrogen atoms plus a oxygen atom
Oxygen (O²¯) is a anion, meaning it has a negative 2 charge (two extra electrons)
Hydrogen (H+) is a cation, it has one less electron in its atom
In water theres 2 H+ ions (2+ charge in total ) and 1 O²¯ ions (2- charge) , making the charges balance out and become neutral
Even though H20 is a neutral charged molecule, oxygen has higher electronegativity than hydrogen, making hydrogen comparatively positive to its oxygen atom

Sickle cell anemia is a recessive trait in humans. In a cross between two parents who are heterozygous.a. Trueb. False
Answer:
True
Explanation:
This is because in the two hetero zygote parents the SS traits are dominated by the dominant A geneotype. Therefore in the AS parents the S-genotype could not manifest, and therefore recessive.
However,when the two recessive genes are crossed in the parents at meiosis 1,the recessive genes were randomly selected to give the SS genotype to the parents.This is an example of autosomal recessive pattern. The chances of inheritance of the gene for the two parents is 25% based on Mendelian's patterns
it is an inherited disorder in which the the percentage of normal biconcave shape Hb is low in the blood, but more of sicked shape ,therefore given the blood of the individual sickle shaped RBCs. It is due to genetic mutation due to single nucleotide substitution of amino acid Glumatic acid with Valine.
The reduction of the surface area for the transport of oxygen,leads to the deficient oxygen supplies to the tissues,and clogging of blood vessels by sickle rbc leading to pains

Which key feature of living organisms is best described as the transmission of DNA from parent to offspring?
Answer:
But what were the key scientific discoveries that helped establish these principles? As it turns out, the connections between genes, chromosomes, DNA, and heredity were ... each parent contributed a form of element to the resulting offspring. ... The most remarkable feature of both Mendel's and Darwin's proposals is that ...
Explanation:
Inheritance is the key feature of the living organisms which can be best described as the transmission of DNA from parent to offspring. Thus, the correct option is C.
What is Inheritance?Inheritance is the process through which the genetic information is passed on from the parent generation to the child. This is why, the members of the same family tend to have similar kind of characteristics.
Genetic information is the DNA or chromosomes which is transferred from the parents to offspring through fertilization of gametes. Gametes are the haploid cells which contain genetic information from both the parents which combine to form an offspring with characteristics similar to both the parents.
Therefore, the correct option is C.

A recessive allele inherited in a Mendelian manner causes the disease cystic fibrosis. A phenotypically normal man whose father had cystic fibrosis, and a mother who comes from a long line of non-affected people, marries a phenotypically normal woman from outside the family. If the frequency in the general population of heterozygotes for cystic fibrosis is 1 in 25, what is the chance that the couple's first child will have cysitc fibrosis
Answer:
The chance that the couple's first child will have cystic fibrosis = 1/100
Explanation:
Since both parents are phenotypically normal, it means that they are both heterozygous for cystic fibrosis.
The probability of a cross of two heterezygotes for a recessive allele to produce an offspring having two recessive alleles is 1 : 4 in accordance with Mendelian inheritance.
The initial probability of the couple's first child to be have two allelic pairs for cystic fibrosis = 1 : 4.
However, the frequency in the general population of heterozygotes for cystic fibrosis is 1 in 25.
Therefore, the chance that the couple's first child will have cystic fibrosis = 1/4 * 1/25 = 1/100
The LLQ is located
___ to the LUQ.
anterior
posterior
Superior
Distal
Inferior
The anatomical terms are used to define the anatomical positions. The LLQ (Left lower quadrant) is located inferior to the LUQ (left upper quadrant). Thus, option e is correct.
What are anatomical terms?Anatomical terms are used to define the exact position and location of the organs and the structures of the body in reference to each other. They are the directional terms that provide the details of the direction an organ is situated at.
The directional anatomical terms include superior, inferior, posterior, anterior, distal, proximal, caudal, occipital, peripheral, central, etc. The LLQ (Left lower quadrant) is the abdominal section that is located below the LUQ (left upper quadrant).
The anatomical term inferior is used to show the structure that lies below the reference organ. On the other hand, the superior shows above, the posterior shows behind, the anterior shows the front area, and the distal shows structures located further away from the origin.
Therefore, option e. the left lower quadrant is inferior to the left upper quadrant.
