If gray wolves were to go extinct, what would be the two most likely effects
on the ecosystem?
When the gray wolves go extinct, the biodiversity in the ecosystem is decreased and the red fox population is also decreased.
What is the food web?The food web shows all the possible feeding relationships in the ecosystem. The long web shows interrelationships between living things. We can see that the chain where the gray wolves also includes the beover and the red fox.
Hence, when the gray wolves go extinct, the biodiversity in the ecosystem is decreased and the red fox population is also decreased.

Which structure does the immune system target in type 1 diabetes?
a. beta cells of the pancreas
b. liver cells that release glucose
c. insulin receptors on fat cells
d. red blood cells in the bloodstream
Answer:
The thymus plays an important role in deletion of potentially autoreactive T cells. However, the presence of islet-specific T cells in the circulation of type 1 diabetes patients and healthy subjects indicates that the thymus is not capable of efficiently deleting all autoreactive T cells (Mathis and Benoist 2009).
Explanation:
Answer:
A: beta cells of the pancreas
Explanation:
Type 1 diabetes makes the pancreas produce little to no insulin.

A species of beetle can be either black or brown in color. The beetle's color is determined by a single gene, and black is recessive to brown. The soil in the area has become darker and closer in color to the black beetles. Which of the following will most likely occur?
Selective pressures will decrease the number of brown beetles.
Selective pressures will increase the number of brown beetles.
Selective pressures will decrease the number of black beetles.
The overall size of the beetle population will continue to decrease over time.
Answer:
the first option
Explanation:
As the soil gets darker, brown beetles become easily recognised by predators (like birds) and will be eaten. Black beetles however, are better camouflaged and will less likely be spotted by the birds. Black beetles will survive and interbreed, allowing the recessive allele to be passed on to upcoming generations.
Selective pressure is what makes the genetic pool shift toward a particular genotype with a particular phenotype (recessive black in this case) that gives the new generations a selective advantage. They're more likely to survive and reproduce. Survival of the fittest.
Genotype- the genetic makeup of an organism (eg: the recessive gene for black; bb)
Phenotype- physical feature of an organism as determined by the genotype (the colour black)
Selective pressures will increase the number of brown beetles. The correct option is 2.
What is Selective pressure?Any factor that reduces or increases reproductive success in a subset of a population may exert evolutionary pressure, selective pressure, or selection pressure, thereby driving natural selection.
Selection pressure can be defined as a force that causes an organism to evolve in a specific direction.
It is not a physical force, but rather an interaction between natural variation in a species and environmental factors that causes certain forms to have an advantage over others.
A beetle species can be either black or brown in color. A single gene determines the color of the beetle, and black is recessive to brown.
The soil in the area has darkened and taken on the color of black beetles. Brown beetle populations will increase as a result of selective pressures.
Thus, the correct option is 2.

Write a set of directions for a red blood cell to deliver oxygen to the brain. Lungs heart-brain aorta arteries veins
Answer: How does oxygen get into the bloodstream? Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.OK Our typical red cell passes from the capillary into the venules, and then into veins. It flows back to the right side of the heart, completing the second loop of its circuit [music out]. As we saw, it then travels back to the lungs.The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.

How does the position of Earth and its orbit affect climate change?
Answer:
The Earth's orbit around the Sun is an ellipse, but it does change shape. ... At other times, the ellipse is more pronounced so that the Earth moves closer and further away from the Sun as it orbits. When the Earth is closer to the Sun our climate is warmer and this cycle also affects the length of the seasons.
An organism has many cells, but cannot move. It does not eat food, but cannot perform photosynthesis cither. What kingdom does it belong to? A,Kingdom fungi, B,Kingdom plantae, C,Kingdom Protista D,kingdom Animalia

Complete the passage about the process of subduction.
The subduction of
boundary often forms volcanoes. This phenomenon occurs because the underground pressure squeezes water out of the dense crust, and this water works its way into the mantle. The water
the mantle and allows for the creation of magma.
The collision between an oceanic and a continental plate, or two oceanic plates originate volcanoes. a) oceanic crust at convergent boundary b) heats up.
What are convergent boundaries?Collision area between two plates. Two continental plates might collide, or two oceanic plates, or one oceanic plate with a continental one.
In the last two cases, the thicker and older plate subduces under the other plate, and magma rises to the surface by crevices. The Himalayas and Los Andes are examples of these collisions.
Plates' movement might produce earthquakes. Also, collisions create volcanic arches and continental arches.
When one of the plates sinks under the other one, it reaches a depth where it melts and magma rises. Volcanoes get formed on the superior plate since magma flows over it.
The subduction of oceanic crust at convergent boundary often forms volcanoes. This phenomenon occurs because the underground pressure squeezes water out of the dense crust, and this water works its way into the mantle. The water heats up the mantle and allows for the creation of magma.

When heat is introduced to matter, what happens to the matter at the molecular level?
Explain in science
Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

(Punnett square and chart attached)
Explanation:
1. The father is a non-roller, as was given in the question. Remember that a phenotype is the physical trait displayed by an organism.
2. In order for the father to be a non-roller, the recessive non-roller allele would have to be expressed. In order for this to happen, he would need two recessive alleles.
3. The gene for tongue rolling is dominant, so if the mother is heterozygous (she has one dominant allele and one recessive allele), then she will be a tongue roller.
4. The mother has a dominant allele and a recessive allele.
5. 50% of the offspring have the Rr genotype and 50% have the rr genotype. This means that there is a 50% of having a tongue-rolling child and a 50% chance of having a non-rolling child.
6. Because the possibility of the offspring having either genotype is 50/50, the ratio would be written as 1:1. Both outcomes are equally likely.
7. Because the possibility of the offspring having either phenotype is 50/50, the ratio would be written as 1:1. Both outcomes are equally likely.
