9. What vascular plant tissue is made of dead cells? stems O phloem ay leaves O xylem Today
Answer:
Xylem, it's a tissue which is made up of dead cells.
Sclerenchyma- The cells of this tissue are dead. They are rigid, contain thick and lignified secondary walls. Their main function is to provide strength and support to parts of the plant.
Xylem is vascular tissue that transports water and dissolved minerals from roots to stems and leaves. This type of tissue consists of dead cells that lack end walls between adjacent cells.

In summer squash, white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over sphere-shaped fruit (d). If a squash plant pure-breeding for white, disk shaped fruit is crossed with a plant pure breedig for yellow, sphere shaped fruit, CACULATE GENOTYPIC AND PHENOTYPIC RATIOS
Answer:
Genotypic ratio = 16 WwDd: 0
Phenotypic ratio = 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit
Explanation:
This question involves two different genes coding for fruit color and fruit shape respectively. The allele for white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over sphere-shaped fruit (d).
According to this question, If a squash plant pure-breeding for white, disk shaped fruit (WWDD) is crossed with a plant pure breeding for yellow, sphere shaped fruit (wwdd), the following gametes will be produced by each GAMETE:
WWDD - WD, WD, WD, WD
wwdd - wd, wd, wd, wd
Using these gametes in a punnet square, all of the offsprings will have genotype WwDd, which is phenotypically white and disk shaped fruit.
The genotypic ratio is 4 WwDd: 0
The phenotypic ratio is 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit.

which protects the dna of a virus
A pilus
B plasmid
C bacteriophage
D capsid
A capsid is a protein shell that protects the DNA of a virus. The correct answer is D) capsid.
What is a capsid ?A capsid is a protein shell that encases the genetic material (either DNA or RNA) of a virus. It is a protective layer that helps the virus survive in harsh environments and protects its genetic material from damage by environmental factors such as UV light, enzymes, and other harmful substances. Capsids can be composed of one or more types of proteins and can take different shapes and sizes depending on the type of virus.
In addition to the capsid, some viruses may also have other protective structures or mechanisms that help them survive in their host environment. For example, some viruses have a lipid envelope that surrounds their capsid, which helps them enter and exit host cells more easily. Others may have other protective layers, such as a protein coat, that help them resist immune system defenses.
It is worth noting that neither A) pilus nor B) plasmid nor C) bacteriophage protects the DNA of a virus. A pilus is a hair-like structure found on the surface of some bacteria that helps them attach to other cells or surfaces, while a plasmid is a small circular piece of DNA that is separate from the bacterial chromosome and may carry genes that confer antibiotic resistance or other advantageous traits.
Hence, Bacteriophages are viruses that infect and replicate within bacterial cells, but they do not protect the DNA of other viruses.

Write two statements expressing the relationships between voltage and current and resistance and current.
Explanation:
The current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant.If we increase the amount of voltage applied, and do not change the resistance, we will also increase the current.Hemophilia is a sex-linked recessive trait. If a man with hemophilia marries a woman who is a carrier for the trait, what are the predicted
phenotypes for their children?
• A1 carrier male: 1 affected male: 1 carrier female: 1 affected female
B 1 carrier male: 1 affected male: 1 carrier female: 1 normal female
C1 normal male: 1 affected male: 1 carrier female: 1 normal female
OD 1 normal male: 1 affected male: 1 carrier female: 1 affected female
Answer:
c i hope it works
Explanation:
No sons of a man with hemophilia will have hemophilia.
All daughters of a man with hemophilia will be carriers (called obligate carriers).
If a carrier has a son, the son has a 50% chance of having hemophilia.
If a carrier has a daughter, the daughter has a 50% chance of being a carrier.

What are the functions of DNA?Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix.
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins.
DNA is made of nucleotides. A nucleotide has two components: a backbone, made from the sugar deoxyribose and phosphate groups, and nitrogenous bases.

Most Swiss starlings produce four to five eggs in each clutch. Starlings producing fewer or more than this have reduced fitness. Which of the following terms best describes this situation? (3 points)
The bottleneck effect will result in a small gene pool with little genetic diversity.
Directional selection will happen because the population individuals will be unable to adapt, leading to extinction.
Disruptive selection will result in the population of birds' risk decline, due to reduced number of eggs.
Genetic diversity allows for birds to produce an ideal number of eggs, which leads to stabilizing selection. I think is D
Answer:
D: genetic diversity allows for birds to produce an ideal number of eggs, which leads to stabilizing selection.
Explanation:
Genetic diversity allows for birds to produce an ideal number of eggs, which leads to stabilizing selection. The correct option is D.
What is genetic diversity?The spectrum of various inherited traits inside a species is referred to as genetic diversity.
There would be many individuals with a wide range of different traits in a species with high genetic diversity. For a group of related species to adapt to changing environments, genetic diversity is mandatory.
Genetic diversity aids the populations to adapt to altering environments. More variation boosts the likelihood that some individuals in a population will have allele variations that are suited to the environment. Those people are more likely to survive and have children with that allele.
Birds can produce an optimal number of eggs due to genetic diversity, which leads to stabilizing selection.
Thus, the correct option is D.
