Keith and Marsha's only child to have a carrier genotype, Jeff, did marry. Cedric remained single due to poor health, and Nita swore off marriage after several bad relationships. Jeff and his wife Adrienne had four children, Angela, Keith, Joyce, and Denise. Although the parents were not expecting it to happen, their only son and their second born girl were born with sickle cell disease. Post- pedigree questions: If you were Ketih and Marsha's genetic counselor, what would you tell them? _____________________________________________________________________________________ Which of the Jackson's grandchildren are definitely carriers? _____________________________________________________________________________________ What is Adrienne's genotype? ________________________________
Answer:
Answer to Question 1:
Sickle cell anemia is a recessive disorder. The fact that one of their children is a carrier means that either of Keith and Marsha is a carrier ot it might be that both of them are carriers of the disease.
Answer to Question 2:
The other two kids of Jeff and Adrienne who don't have the genetic disease are still carriers of sickle cell anemia.
Answer to Question 3:
Adrienne is a carrier of the sickle cell anemia disease as well, just like Jeff.

Red squirrels and gray squirrels have been the native species on an island for many years. A few years ago, black squirrels entered this island. The black squirrel is an invasive species. Invasive species aren't native to the ecosystem. They move into an ecosystem because of natural changes or human intervention. Red squirrels and black squirrels have identical food requirements, but gray squirrels have a different diet. What three effects will these events have on the island's squirrel population?
Answer:
1. There will be direct predation of species.
2. There will be competition for limited resources like breeding sites, prey.
3. Transmission of diseases or they can cause danger to the native species.
Explanation:
Invasive species are species of organisms that are not natural to an ecosystem and move to an ecosystem because of natural changes and human intervention. Islands are prone to the invasion of invasive species because they don't have predators and there is no competition that control populations in their ecosystem. The invasion of black squirrels will lead to competition for limited resources like breeding sites or prey, the black squirrels will begin to predate other squirrels because they have different nutrients requirements and they can transmit diseases to other squirrels if they are carrier.

Which traits would Aristotle have used to classify sharks? Choose more than one answer.
Answer:
The main trait that was different between sharks 14 and 9 was that shark 14 (Mobulidae) has a front with two points that look like horns, whereas shark 9 (Dasyatidae) has a front with no points that look like horns.
Explanation:
The traits that Aristotle would have used to classify sharks are :
Front with points ( hornlike )Front without points Sharks classificationSharks whose front have two points like horns are classifed by Aristotle as sharks 14 (Mobulidae). whlie sharks whose front does not have two points like horns are classifiesd as sharks 9 ( Dasyatidae ). hence the traits that would have been used by Aristotle to classify sharks is the presence of points at the front.
Hence we can conclude that the traits that Aristotle would have used to classify Sharks are Front with points and front without points.

What are the functions of cell?Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
Cells provide structure and function for all living things, from microorganisms to humans. Scientists consider them the smallest form of life.

Giraffes with short necks lived in arid regions and fed on grasses. Over time, grasses disappeared, forcing giraffes to eat from trees. Mutations in the genome led to some giraffes inheriting the trait for long necks. Over time, there were more giraffes with long necks in the region. What are the two reasons for the change in the population of giraffes?
Answer:
Two reasons are that the grasses they ate disappeared which caused some to die, but some lived and ate from trees and reproduction and such happened.

Which characteristic makes fungi similar to plants?
Answer:
They are both non-mobile and eukaryotic.
Explanation:
Plants and fungi both remain stationary. They do not move around for their food. Another similarity is that they both are made up of eukaryotic cells, meaning they contain a nucleus.
Answer:
While both are eukaryotic (both have nucleus) and don't move, plants are autotrophic, making their own energy - and have cell walls made of cellulose, but fungi are heterotrophic, taking in food for energy (so they eat dead and decaying food), and have cell walls.

How do the data that Samantha obtained help explain the way that the body maintains homeostasis during exercise? Include the activities of at least three body systems in your explanation.
Answer:
the way that the body maintains homeostasis during exercise is the removal waste product such as carbon dioxide gas which is produced during cellular respiration.
Explanation:
During exercise, the body needs more oxygen and nutrients. For this purpose, energy is released in the process of cellular respiration. The product of cellular respiration the generation of energy in the form of ATP and carbon dioxide gas. ATP is used by the body while carbon dioxide is removed from the body during breathing. During exercise, the glucose is provided by the digestive system to the mitochondria of the cell and the waste product is removed through respiratory system of the body while the circulatory system sends energy molecules where it is needed in the body and carbon-dioxide to respiratory system for removal.

Why are models important ?
Explanation:
Models are important in science because a model is a representation of an idea or an object or systems that could be used to describe something that cannot be experienced directly
Answer:
Models allow the scientist to describe objects that are too large or too small to be seen normally, things that don't exist anymore, things that have not been created, and events that occur too slowly or too quickly to be seen. Models also communicate ideas that might be difficult to describe otherwise.
Explanation:

Another way of saying it would be:
Models are important because it allows scientist to help people better understand a subject that they wouldn't be able to understand, due to that fact that other variables prevent the subject from easily being seen and observed. Models also allow you to explain things in a way that is easier and simpler to explain.
