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.

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.

Hormones are substances that administer the human body having several different and essential functions for the proper functioning of the body. There are several different types of hormones and they are classified into four groups called peptides, steroids, amines and eicosanoids.
Peptides are hormones that have 3-20 amino acids. Among these hormones we can mention insulin, glucagon and somatostatin.
Steroids are hormones produced from cholesterol. Among them we can mention Cortisol, Aldosterone and Testosterone.
Amine hormones are those that are released into the thyroid and adrenal glands. These hormones circulate freely in the blood. Among them are epinephrine and norepinephrine.
Eicosanoids are the hormones derived from arachidonate. Among them are the hormones called prostaglandins, thromboxanes and leukotrienes.

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.

An increase in heart rate will most likely result in
O (1) a decrease in metabolic rate
O (2) an increase in pulse rate
O (3) an increase in cell division
O (4) a decrease in body temperature
Answer:
O (2) an increase in pulse rate
An increase in heart rate will most likely result in an increase in pulse rate. So, the correct answer is (B).
What is Heart?Heart is a fist shaped organ which pumps blood throughout your body present in the centre of the chest tilted slightly towards the left. It is the primary organ of the circulatory system which pump blood around the body as the heart beats. The blood sends oxygen and nutrients to all parts of the body and carries away unwanted carbon dioxide and waste products from there.
Heart has four chambers (lobes) made up of muscles- two on the left side and two on the right made up of three layers of tissue -epicardium, myocardium and endocardium. These layers are surrounded by the pericardium which a thin outer lining protecting the heart.
It circulates abut 5-8 liters of blood. Heart, blood and blood vessels together make the cardiovascular system. Blood is pumped around your body through a network of blood vessels- Arteries, Capillaries and veins. Heart has four valves which act like gates which keep the blood moving in the right direction.
Thus, an increase in heart rate will most likely result in an increase in pulse rate. So, the correct answer is (B).

The sun heats the earth through radiation. Since there is no medium (like the gas in our atmosphere) in space, radiation is the primary way that heat travels in space. When the heat reaches the earth it warms the molecules of the atmosphere, and they warm other molecules and so on.
Tom walked into your office and said he'd been looking forward to talking with you. He said, "I've been feeling really good lately, really good...powerful, strong." Tom, a 54-year old man, was smiling and a bit wide-eyed as he began the conversation. "I'm feeling a real sense of purpose, like I was put here to help people," he said. Tom got further into his recent revelations, going so far as to say he felt "like Jesus Christ, in a way." Tom stood up with excitement as he continued to escalate emotionally and with his gestures. At no point was he threatening, but he was far more animated than ever before. As the conversation progressed, Tom told you that he was thinking about you and how powerful you were, too. He said you were like Thor with his hammer and that the two of you could really do good in the world. Then, giggling and gleeful, he admitted that he was thinking that he actually was Jesus Christ and that he wanted you and your powerful hammer to help him save humanity from those who were trying to control him.

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.
