How can the rate at which bacteria are evolving to be antibiotic resistant be slowed down by humans?
A.
use a variety of different antibiotics
B.
reduce the usage of antiobiotics
C.
apply fewer pesticides to crops
D.
Both A and B
Answer: D. Both A and B
Explanation: Bothe A & B would help with B being the most effective method of slowing antibiotic resistance. Not using antibiotics when not absolutely necessary would be best but when necessary using a variety instead of reliance on a popular few would help.

Describe the characteristics and classification of seedless vascular and nonvascular plants
Answer:
Vascular plants, also known as tracheophytes, are plants found on land that have lignified tissues for conducting water and minerals throughout the body of the plant.
1. These lignified tissues are also called vascular tissue and consist of water-conducting xylem tissue and food-conducting phloem tissue.
2. Vascular tissue forms a central column, also called stele, through the plant axis for the transport of different substances.
3. Vascular plants are said to have a true stem, leaves, and roots due to the presence of vascular tissues.
4. The root is a true root that enables the plant to anchor onto the soil and gets nutrients from it.
5. The leaves are broad and have stomata that work for gas exchange and support transpiration.
6. The stem of vascular plants is multilayered with vascular tissue that helps in the protection and conduction of food and water.
7. The arrangement of these issues might be different in a different group of plants as it depends on the pattern of division of cells.
8. The xylem is composed of non-living matter, tracheids, and vesicles, hardened by lignin that provides a stiff structure to the tissue. 9. The phloem, on the other hand, contains living sieve elements that are not lignified.
10. Vascular plants are capable of surviving on land due to their ability to transport food, water, and mineral to different parts of the plant by creating pressure through the tissues.
11. Besides, they also have several modifications that facilitate their survival on land.
12. Another essential characteristic of vascular plants is that the principal generation phase in these plants is the sporophytic phase where they produce diploid spores.
13. Vascular plants are tall and large in size compared to the non-vascular plants because of their ability to transport necessary substances to all parts of the body via vascular tissue.
14. It is believed that vascular plants are a more evolved version of non-vascular plants and thus came later in the evolutionary history.
15. Vascular plants are divided into two groups; non-seed plants or lower vascular plants or cryptograms and seed plants or higher vascular plants or phanerogams.
16. The lower vascular plants include plants like ferns that although are adapted to survive on land still have some characteristics of their aquatic ancestry. These plants belong to the group Pteridophyta.
17. The higher vascular plants are numerous and extremely diverse and are further divided into different subgroups.
18.Some examples of vascular plants include maize, mustard, rose, cycad, ferns, clubmosses, grasses, etc.
Answer:
Definition of nonvascular plant
: a simple, low-growing, nonflowering plant (such as a moss or liverwort) that lacks specialized conducting channels for transporting water and nutrients
vascular plants have lignified tissues for conducting water and minerals throughout the plant.

Why does your body need to breathe in oxygen?
a.Your blood uses the oxygen to help it clot and fight disease.
b.Your lungs store oxygen in the alveoli to help absorb carbon dioxide.
c.Your cells use the oxygen to break down sugar and produce energy.
d.Your heart uses the oxygen to make blood.
Answer:
c.Your cells use the oxygen to break down sugar and produce energy.
Explanation:
Oxygen is a key reactive involved in breaking down glucose molecules during the process of aerobic cellular respiration. As a product of this process, the cells produce Adenosine triphosphate (ATP) molecules, the energy coins of the cell which are used to carry out cellular activities. By breathing the oxygen molecules enter into the lungs (air sacs) and then they are carried out by the blood vessels around the body in the bloodstream, reaching each cell to be used during aerobic cellular respiration.
A healthy college student went to Colorado at the end of the school year for a vacation. While there, he drove to the top of Pike's Peak, a tall mountain. During his first hour on the peak, he walked about but had to sit down to rest three times. The last time was in the weather station. He glanced at the barometer hanging over his head. It read 450 mm Hg. (total Atm pressure). Explain two physiological responses that would increase the amount of oxygen delivered to her tissues.
Answer:
Due to sloppy geography and lower air pressure.
Explanation:
Walking on the sloppy and low pressure are the two physiological responses that increases the amount of oxygen given to her tissues. Walking on the steep and sloppy region requires high amount of energy so for that energy the body needs more and quick oxygen in order to breakdown of glucose for the release of energy that can be used for walking while on the other hand, the low atmospheric pressure have low amount of oxygen in the air so the person needs more oxygen for its breathing so the person breathe air fastly to supply optimum amount of oxygen to the body.

The cell knows which amino acids are to be attached to the ribosome during translation by reading the ______________ found on the mRNA
Answer:
The correct answer is - codons.
Explanation:
Each mRNA is made up of the codons that are complementary to the DNA sequence during transcription and once it binds with the ribosome, mRNA strand codes are read by tRNA in triplet code that decides which amino acid would be bind to the ribosome during translation to synthesize the polypeptide chain. For instance, if mRNA has CCG codon then tRNA should have GGC anticodon should have bound.

The elements potassium and rubidium are alkali metals.
How do alkali metals differ from other metals?
O A. They have higher densities.
OB. They have higher reactivities.
O c. They have higher melting points.
D. They have higher electronegativities.
Answer:
D
Explanation:
The alkali metals have the high thermal and electrical conductivity, lustre, ductility, and malleability that are characteristic of metals. Each alkali metal atom has a single electron in its outermost shell. This valence electron is much more weakly bound than those in inner shells.
Alkali Metals have higher reactivities. Therefore, option (B) is correct.
Alkali metals, including potassium and rubidium, differ from other metals primarily in terms of their reactivity. Alkali metals are highly reactive and readily react with other elements or compounds, especially water and oxygen. This reactivity is due to their low ionization energies and the tendency to lose their outermost electron to achieve a stable electron configuration.
In contrast, other metals may have lower reactivity or may require more energy to undergo chemical reactions. While the density, melting points, and electronegativities can vary among different metals, the characteristic that sets alkali metals apart is their high reactivity, which is a result of their electron configuration and the ease with which they can form positive ions.

Ocean ecosystems are most impacted by which two factors?
A. Number of fish and salinity
B. Pollution and boat traffic
C. Depth and distance from shore
D. Light and nutrient availability
Answer:
B. Pollution and boat traffic
Explanation:
The ocean ecosystem is most impacted by pollution and boat traffic. Thus, option C is correct.
What is an ocean ecosystem?Aquatic environment with concentrated saline conditions, including open oceans, deep sea oceans, and coastal marine ecosystems, each with assorted physiological and biological features.
Marine ecosystems are consist of biotic and abiotic factors. Biotic factors include living organisms, including plants, animals, and microorganisms. Abiotic factors include non living things, including amount of nutrients, availability of gases, sunlight, temperature, and pressure.
But pollution and boat traffic has direct and deadly effect on wildlife. after consumption of microplastic thousands of animals live sea turtles and seals are killed. Nitrogen emitted by boats in oceans disturbs the ecosystem. Therefore Option C is correct.
