The Perennial Pepperweed was first introduced in Las Vegas during the 19th century. This weed damages the soil and makes it impossible for other plants to grow around it. It has been continuing to spread in southern Nevada and threatens many organisms in the area. The Perennial pepperweed is an example of:

(A) An endangered species.
(B) An invasive species.
(C) An abiotic factor.
(D) A non-living factor.

Answers

Answer 1

Perennial pepperweed is an invasive species, as shown in option B.

How to define an invasive species?Organisms that originated in one area and spread to other areas.Organisms that cause problems in the area where they invaded.Organisms compete with local species for the same natural resources.

We can determine that the Perennial pepperweed is an invasive species because despite having been created in Las Vegas in the 19th century, it is invading other areas, mainly in southern Nevada, where it causes problems for local plants.

This is because the Perennial pepperweed takes over the soil, damaging it and preventing other species from growing.

You decide to conduct a genetic analysis of these mutant lines by crossing each with a pure-breeding wild-type line. the numbers in the f2 indicate the number of progeny in each phenotypic class.

Answers

The following represents the type of mutant allele:

Forked: The mutant allele is dominant to its corresponding wild-type allele. Twisted: The mutant allele is neither totally dominant nor completely recessive to its corresponding wild-type allele.Pale: Neither the mutant allele nor its corresponding wild type allele is dominant or recessive.

Is an allele dominant or recessive?An allele cannot be "dominant" or "recessive" by definition. These phrases instead describe the interaction between two alleles. A heterozygote is used to assess this relationship since it has one dominant allele and one recessive allele, with the dominant allele determining the phenotype of the heterozygote.The phenotypes of some heterozygotes fall somewhere between those of the two homozygotes. Because neither allele is totally dominant over the other, this scenario is the result of partial dominance.

The __________ , on the posterior thorax, are roughly triangular in shape. They have no direct attachment to the axial skeleton but are held in place by trunk muscles.

Answers

The scapulae, on the posterior thorax, are roughly triangular in shape. They have no attachment to the axial skeleton but are held in place by trunk muscles.

The bone that connects the clavicle (the collar bone) with the humerus (the upper arm bone) is the scapula (in plural, scapulae), or shoulder blades. The word 'scapular' originates from a Latin word meaning 'trowel' or 'shovel', because of its resemblance to a shovel.

The scapula is a triangular shaped bone that can be found posterior (at the back) to the thorax. Although they are not attached directly to the axial skeleton, they are necessary for the smooth motion of the upper extremity and several other motions associated with daily living, for example, shrugging of the shoulders. The pectoral girdle and chest muscles assist with the protraction and retraction and retraction of the scapula. It is also essential to the stability of the shoulder point as a whole.

Emphysema and chronic bronchitis are the two most common conditions that contribute to COPD

Explanation:

Breathlessness is a symptom of the lung disease emphysema. Alveoli,  also known as the lungs' air sacs, suffer damage in those suffering from emphysema. These air sacs' internal walls weaken & burst with time, resulting in the formation of bigger air voids rather than numerous, tiny ones.

Emphysema symptoms could include the coughing, sneezing, breathlessness, tightness in the chest, as well as a higher production of mucus. Usually, symptoms may not appear till the tissue of lungs has just been damaged to 50% or above.

A severe cough that lasts longer than three months and persists for minimum two years in a row qualifies as chronic bronchitis. There may be times when the cough and perhaps other signs of chronic bronchitis get worse.

Which animal has a more efficient microbial fermentation system, sheep or horse? explain.

Answers

Sheep has more efficient microbial fermentation system than horse.

Based on the characteristics of their digestive fermentation sites, animals can be categorized as foregut or hindgut fermenters. In contrast to a hindgut fermenter, which has larger fermentation compartments in the cecum and/or colon, a foregut fermenter by definition has a pre-gastric fermentation chamber. Horses display hindgut fermentation, whereas sheep have foregut fermentation. Hindgut fermentation is a digestive process that occurs in creatures with single chambered stomachs, whereas foregut fermentation is a form of cellulose digestion seen in ruminants, who have a four chambered stomach.

Foregut fermentation is often thought to be more effective than hindgut fermentation based on the stomach compartment. Therefore, sheep has a more efficient microbial fermentation because it exhibits foregut fermentation.

Which statements accurately describe osmosis? Check all that apply.

Answers

The first, fourth, and fifth statements accurately describe osmosis.

The net movement of solvent molecules through a semipermeable membrane is known as osmosis. Since the movement is downward and goes from greater to lower concentration, it is comparable to diffusion. However, in osmosis, the movement must take place through a membrane that is semipermeable or selectively permeable. It cannot be referred to as osmosis without this component.

Osmosis is about the net movement of the solvent molecules (not the solute), whereas diffusion is frequently depicted as the net movement of solutes between two solutions (solvent such as water molecules). The water must migrate in order to equalise the concentrations of the two areas due to the different concentrations of water molecules on the two sides of the membrane.
