Answer: A vascular plant is any one of a number of plants with specialized vascular tissue. The two types of vascular tissue, xylem and phloem, are responsible for moving water, minerals, and the products of photosynthesis throughout the plant. As opposed to a non-vascular plant, a vascular plant can grow much larger.
Explanation: The ferns, gymnosperms, and flowering plants are all vascular plants. Because they possess vascular tissues, these plants have true stems, leaves, and roots. Vascular tissue forms a central column, also called stele, through the plant axis for the transport of different substances. Vascular plants are said to have a true stem, leaves, and roots due to the presence of vascular tissues.

10. What would be an agricultural disadvantage to having a planting soil with high permeability?
Answer:
Excessive water loss
Explanation:
If the soil was super permeable than water would drain faster which could lead to excessive water loss which would not be good for crops
Having planting soil with high permeability will deprive crops of the necessary water and nutrient for growth.
Highly permeable soils have no capacity to retain water. they lose water at a very fast pace.
Lack of water retention means that the roots of plants will not be able to conduct the necessary water for metabolic activities in plants.
Thus, the growth and overall well-being of plants planted in such soils will be limited.

Which of the following is true of DNA and RNA nucleotides? (4 points)
Both contain a sugar and a cytosine nitrogenous base.
Both contain a sugar and thymine nitrogenous base.
Both contain deoxyribose sugar and uracil nitrogenous base.
Both contain ribose sugar and cytosine nitrogenous base.
Answer:
Both contain a sugar and a cytosine nitrogenous base.
Explanation:
DNA and RNA are both nucleic acids. However, the nucleotides bases) that make up each molecule have slightly different structures.
DNA stands for deoxyribonucleic acid because the sugar in the nucleotides is deoxyribose sugar.
RNA stands for ribonucleic acid because the sugar in the nucleotides is ribose.
DNA contains the bases cytosine, guanine, adenine, and thymine.
RNA contains one base different, it has cytosine, guanine, adenine, and uracil.
Therefore, they contain different sugars, but they both contain a cytosine nitrogenous base.
Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere. Once the chromosome has split, each chromatid is called a daughter chromosome. At the end of cytokinesis, how many daughter chromosomes will be found in each cell? Explain.
Answer: 2
Explanation:
Each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.
At the end of cytokinesis, there will be 46 daughter chromosomes in each cell.
MITOSIS:Mitosis is the type of cell division that results in two daughter cells that are genetically identical to one another. According to this question, human cells possess 46 chromosomes, which divides during mitosis into daughter chromosomes called chromatids.Therefore, after cytokinesis, 46 daughter chromosomes will be present in each cell in order to maintain the chromosome number of the parent cell.

In order to replicate behavior, one must retain it in memory. True or false?
Answer:
True
Explanation:
"One must retain behavior in memory in order to duplicate behavior," is a true statement.
What is a long term memory?Memory can be divided into two distinct classes: short-term and long-term.
After the information has been encoded in the appropriate manner, it is stored in the long term memory for use at a later time. As a consequence, the assertion that "in order to repeat behavior, one must retain it in memory" is validated as being correct.

What is genetic drift? A) In a population, it is the changes in allelic frequencies of a gene that are due to chance. B) A random error/change in the DNA sequence. These may be inherited or occur in cells during the lifetime of the organism. C) Also known as gene flow.

C. vehicle hazards
D. bins and silos
Answer:
I think that this might be your answer :) I tried hope this helps !
Explanation:
A) Heat exposure Because In terms of weather Heat: Inhaling hot air, induces airway constriction making it difficult to breathe.
Also Of course, it's known that smoke from fire can have a terrible effect on your lungs. It can restrict oxygen flow, which can and most likely be deadly. So the exposure to the heat will distract them cause they cant breath while they work .

Answer:
There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material.

Answer:
the allele combination for a trait
Explanation:
The genotype describes which alleles (versions) of a gene an organism has. Diploid organisms, such as humans, have two copies of each gene. Sometimes these alleles are the same and the individual is h0m0zygous for that gene. If they are different, the individual is heterozygous for that gene.

O
D. DNA has thymine and RNA has uracil.
Answer:

The statement (D) is correct. DNA has thymine and RNA has uracil.
What is DNA and RNA?DNA and RNA are both types of nucleic acids, large molecules that are made up of monomers called nucleotides. Nucleic acids are used to store genetic information, which the cell uses to make proteins.
Moreover, nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.
Hence, DNA is a double-stranded molecule that has a long chain of nucleotides. RNA is a single-stranded molecule which has a shorter chain of nucleotides. DNA replicates on its own, it is self-replicating. RNA does not replicate on its own.
