Global measurements indicate that, in the late 2000s, sea levels steadily rose. Rising sea
levels lead to the migration of marshlands further inland. The environmental changes
caused by rising sea levels have the potential to?
O increase the stability of marsh habitats.
decrease the stability of marsh habitats.
O increase the biodiversity of organisms in marsh habitats.
alternately increase and decrease the biodiversity of marsh habitats.
Answer:
My Game is José Fernando Tengo 12 YEARS OLD
The environmental changes caused by rising sea levels have the potential to alternately increase and decrease the biodiversity of marsh habitats.
What is Biodiversity?Sum total of all the varieties of living organisms in a particular space, is known as its biodiversity.
As the sea levels steadily rose, it will firstly increase the biodiversity of marsh habitats, but sea level constantly rising, will affect its biodiversity, and organism that is native to marshy habitat should be eliminated while those organisms that are able to survive in inland habitat will migrate into it, overall causing the decrease meant of biodiversity of marshy habitat.
Therefore, the environmental changes caused by rising sea levels have the potential to alternately increase and decrease the biodiversity of marsh habitats.

Describe the relationship between the sickle cell phenotype and hemoglobin’s structure and function
Answer: Explanation:
Sickle hemoglobin differs from normal hemoglobin by a single amino acid: valine replaces glutamate at position 6 on the surface of the beta chain. Therefore the red blood cell bends differently giving it a sickle shape
Answer:
Explanation:
Sickle cell disease is a group of disorders that affects hemoglobin, the molecule in red blood cells that delivers oxygen to cells throughout the body. People with this disease have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape.
Signs and symptoms of sickle cell disease usually begin in early childhood. Characteristic features of this disorder include a low number of red blood cells (anemia), repeated infections, and periodic episodes of pain. The severity of symptoms varies from person to person. Some people have mild symptoms, while others are frequently hospitalized for more serious complications.
The signs and symptoms of sickle cell disease are caused by the sickling of red blood cells. When red blood cells sickle, they break down prematurely, which can lead to anemia. Anemia can cause shortness of breath, fatigue, and delayed growth and development in children. The rapid breakdown of red blood cells may also cause yellowing of the eyes and skin, which are signs of jaundice. Painful episodes can occur when sickled red blood cells, which are stiff and inflexible, get stuck in small blood vessels. These episodes deprive tissues and organs, such as the lungs, kidneys, spleen, and brain, of oxygen-rich blood and can lead to organ damage. A particularly serious complication of sickle cell disease is high blood pressure in the blood vessels that supply the lungs (pulmonary hypertension), which can lead to heart failure. Pulmonary hypertension occurs in about 10 percent of adults with sickle cell disease.

What are ethical concerns in using animals for research?
Select all that apply.
Animals cannot consent to being used in experiments.
Animals are ideal biological models for experiments
Many animals can be studied at one time.
Some animals may have adverse reactions.
Answer: Animals cannot consent to being used in experiments.
Explanation:
Animals are not suitable options for the biological research as they are getting extinct and their population size is getting decreased. Option A is correct.
What are extinct species ?These are the species that are getting diminished from planet because of certain factors such as loss of habitat and many other crucial factors that affecting their growth.
Animals can not be used in the biological research as they are not able to speak the language which is understood by humans and ideally it is not right to do dissection over living beings.
Animals earlier were definitely considered for the experiment but the awareness of ethics and sensitivity of the issues is bringing down the ban on the animal crimes along with the lab research.
Ethical concerns are as well that without God's permission it is not right to harm the living beings.
Therefore, option B is correct.

Madeleine and jared have a child together. Madeleine has type A blood, Jared has type B blood and their child has type O blood. Jared is questioning the paternity of the child. Determine if Jared could be the father of the child. Can he be the father, Why or why not.
Jared could be the father. Types A and B blood types in parents (in this specific way, that being type A maternally and type B paternally) will result in children with either A, B, AB, or O blood types. The blood types are compatible thus, Jared could absolutely be the father.

A liquid has a density of 11g/mL. If you have 35mL of the liquid, what would its mass be?
Answer:
use the equation below
Explanation:
density=mass/volume
A liquid has a density of 11g/mL. If you have 35mL of the liquid, the mass of the liquid will be 385 grams.
What is density?"Density is the mass per unit volume". Density is a scalar quantity. It is denoted by d and the symbol for density is given as rho, a Greek symbol. Density is calculated as mass divided by volume.
"Mass is the quantity of matter in a physical body". The product of the molar mass of the compound and the moles of the substance are defined as mass.
Volume is the space occupied by a three-dimensional object.
Given that, the volume of liquid is 35mL
The density of the liquid is 11g/mL
The mass to be calculated
The formula to calculate the mass is
mass = volume x density
mass = 35 x 11 = 385 grams
Thus, the mass of the liquid will be 385 grams

Velocity is the variable which is changing during motion of skater.
Impact of velocity on energyVelocity is the variable which is changing when the skater moves up and down the track because moving upward on the slope decrease the speed of the skater while on the other hand, velocity increases when moving downward on the slope.
Mass of the body which is skating remain constant or can't change with height. Mass is the amount of matter present inside the body so we can conclude that velocity is the variable which is changing during motion of skater.
