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.
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.

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.
Some diseases are diagnosed by looking for antibodies in the patient’s blood. Explain what a positive finding of antibodies means.
Answer:

Speckled trout and red drum both prey on mullet along the Texas coastline. Dead zones are caused by excessive nutrient pollution, along with other factors that deplete the oxygen from the water. What likely effect would increasing dead zones have on the populations of speckled trout, red drum, and mullet?
Answer:
All Three Populations Would Decrease
Explanation:
Dead zones have little to no life in them, and besides the fact that this would mean the popoulations of all of them would just be down because of this, mullet will die out due to nothing to feed on, which will make drums and trout also die out, so all of the populations would go down.
The effect that would be increasing dead zones have on the populations of speckled trout, red drum, and mullet is that the population of all three species would get decrease.
What do you mean by Prey?Prey may be defined as an animal that is hunted and killed by another for food.
Dead zones lead to a decline in biodiversity of that area, due to the excessive nutrient pollution and depletion of oxygen. If the members of mullet species get reduced in an environment, species of speckled trout and red drum feel the shortage of food, and hence they also get eliminated or die from the surrounding.
Therefore, the effect that would be increasing dead zones have on the populations of speckled trout, red drum, and mullet is that the population of all three species would get decrease.

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.
