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.

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.
Explanation:

A) they formed in a vigorous river environment.
B) They formed in a shallow water environment.
C) they formed in a desert environment.
D) They formed in a deep ocean environment.
B, becauuse if the water dried up and left the mud to dry, mud will crack. but water would have to evaporate
The geologists notes the presence of mud cracks in the rock layer. the environment in which the footprints were most likely made They formed in a shallow water environment. hence option B is correct.
What is rock cycle ?Rocks are defined as the naturally formed and non-living earth which are composed by collection of mineral grains held together in a firm, it can be tiny or big.
The Rock cycle is the process where a continuous process occur through which old rocks are transformed into new rock due to cool down of molten magma, when it solidifies become igneous rock.
when the break down of the igneous rocks occur the small particles are transported and deposited which will form sedimentary rocks, When the igneous and sedimentary rocks heated up and under the pressure they change into metamorphic rocks.
The metamorphic rocks are generally subjected under great heat and pressure melt down to form molten magma which again can cool down and solidify into igneous rocks

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.

pollution.
Answer:
The correct answer is - volatile organic compounds.
Explanation:
Fracking liquid waste is a type of waste that is producing during the oil drilling process by hydraulic fracturing. It produces some toxic and carcinogen substances that are needed to treat properly or these will mix with drinking water.
Other than these toxic substances the fracking liquid waste also produce volatile organic compound due to oil drilling which is very harmful to the environment as these organic compounds can evaporate and move to air and atmosphere to contribute to pollution.
