"An advantage of ______ reproduction is that a genetic disorder in a parent might not affect The offspring
Answer:
An advantage of sexual reproduction is that a genetic disorder in a parent might not affect the offspring.
Explanation:
got 100
Answer:
An advantage of sexual reproduction is that a genetic disorder in a parent might not affect the offspring.
Explanation:
Since there are only two types of reproduction, sexual and asexual, andin asexual reproduction, the offspring gets all the qualities of the parent, we can determine that the offspring might not get the genetic disorder from the parent IF it is sexual. That is because there are 2 parents, hence giving a 50-50 chance to get it.
Can someone help me with this question pls (8th grade science)
Answer:
C
Explanation:
The exerpt states that movements in the Earth's crust (unbalance) causes Earthquakes. When it's balanced, there is no plate movement.
Answer: c
Explanation: if there is no plate movement that means that there is a balanced force there is nothing that is disrupting it. but if there's an earthquake in that means that there are unbalanced forces in that they cause an earthquake. a force is balanced if the two individual forces are of equal magnitude and of the opposite direction. And an object is said to be acted upon by an unbalanced force when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.

Read the excerpt from "Bone Detective," by Lorraine Jean Hopping. While the dentist worked on the tiger’s teeth, Diane made an alginate impression of one of its huge paws. Then, the dentist used two cupped hands to pull the tongue out of the big cat’s mouth. The heavily muscled organ was almost as long as her foot. With the dentist still holding the tiger tongue in both hands, Diane quickly went to work. The pink surface was rough, like sandpaper, but floppy and wet. She coated the top with alginate and waited for it to set. Her 15 minutes were almost up. The tiger, so calm and soft, would soon wake up and be dangerous again. Slowly and carefully, Diane peeled off the soft impression to avoid tearing it. Based on this excerpt, what is the author’s attitude toward Diane France? The author feels Diane is rough and impatient in her work with the tiger. The author feels Diane is skillful and careful in her work with the tiger. The author feels Diane is anxious and distracted in her work with the tiger. The author feels Diane is light-hearted and humorous in her work with the tiger.

What would happen if a new cell does not contain chromosomes ( best answer with explantion will get brainliest)
a. the new cell will not have instructions on how to function
b.nothing, chromosomes are not important to cells
c. the new cell will reporoduce uncontrollably
d.the new cell wil grow but cannot duplicate itself in the future
a. the new cell will not have instructions on how to function
Because all the genetic material is stored in the chromosomes. Thus, all information is in it.
Answer:
a. the new cell will not have instructions on how to function
Explanation:
Genetic information contained within DNA molecules regulates cell growth, replication, and cell repair. The long-chain, helical macromolecules of these deoxyribonucleic acids are formed from complex sequences of nucleotide monomers- secondary strands contain a complementary sequence joined to the leading strand by hydrogen bonding.
Chromosomes are the double-stranded DNA helixes wound around small molecules called histones. Genes or sequences of DNA encode instructions for the cell, in the form of proteins. This occurs via: the transcription processes, translation to become proteins, defining physical traits or phenotypes.

5. which two processes provide the glucose and nitrogen used to form amino acids in plants?
A. photosynthesis and nitrate absorption
B. cellular respiration and the citric acid cycle
C. photosynthesis and dehydration synthesis
D. glycolysis and nitrate absorption
Answer:
1. ATP
Explanation:
Cellular respiration may be defined as the chemical process of breakdown of food in the cell with the liberation of energy in the form of ATP.
Photosynthesis is a chemical process through which green plants most photosynthetic algae synthesize their own food in the form of glucose. While nitrate absorption is the process through which nitrogen in the soil is significantly absorbed by the root of plants in form of nitrates.
Fermentation is initiated with the process of glycolysis, but it does not involve the upcoming two stages of aerobic cellular respiration such as the Krebs cycle and oxidative phosphorylation.
Therefore, each of the above questions is well described above.

What makes the structure of Carbon so unique? Why is Carbon considered the building block of all life? (3 sentence minimum answer)
Answer:
The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules.
All living things contain carbon in some form. Carbon is the primary component of macromolecules, including proteins, lipids, nucleic acids, and carbohydrates. Carbon's molecular structure allows it to bond in many different ways and with many different elements.

Which career combines DNA technology and forensics? pharmaceuticals paternity testing environmental studies genetics
Answer:
B. Paternity
Explanation:
Edge 2020
The career that combines DNA technology and forensics is paternity testing. The correct option is B.
What is paternity testing?DNA testing examines an individual's DNA banding patterns to determine the identity or mutations of a specific gene.
Paternity testing is a type of DNA testing that is used to determine paternity and the true nature of a relationship.
The lab compares tissue samples from the mother, the child, and the man to determine what unique characteristics known as genetic markers the child shares with the mother and the man who may be the father.
The chromosomes that determine the gender of the baby (X and Y chromosomes). The mother's egg typically contributes an X chromosome, while the father's sperm contributes either an X or a Y chromosome.
These tests are extremely accurate in determining whether a man is the biological father of a child.
Thus, the correct option is B.
