Answer: How might it be possible for you to show a trait when neither of your parents show the same trait. It can be carried to you when the chromosomes combine even if the parents don't possess the same trait It can skip and be dominant for you so you would be able to see it in your genetic make up.

Algae possess chlorophyll in their cells. They use carbon dioxide in a manner that is analogous to how we use food. Thus, option B is correct.
What is a characteristic feature of algae?By converting light energy to chemical energy through the process of photosynthesis, carbon dioxide and water are transformed into organic molecules.
Nearly all algae engage in the process, and in fact, much of what is currently known about photosynthesis was first uncovered through research on the green alga Chlorella.
Like other plants, algae benefit from sunlight, therefore denying them of it will limit or even completely stop their growth. For several days, completely shading the tank or aquarium from light is essential.
Therefore, algae require sunshine because algae can photosynthesize, or use sunlight to change carbon dioxide into biological material.

3. Compare and contrast the movement produced by each of the three types
Answer:
strike-slip is when the blocks have mostly moved horizontally, normal is when a dip-slip fault in which the block above the fault has moved downward relative to the block below, and thrust is when the hanging wall moves up relative to the footwall.
There are three faults. Normal faults originate from the divergent boundary. Reverse faults originate from the convergent boundary. Strike-slip fault originate from transforming boundary.
What are the three types of fault?We can differenciate three types of faults,
Normal fault ⇒ originate from divergent movementReverse fault ⇒ originate from convergent movementStricke-slip fault ⇒ originate from transforming movementWhat are the boundary types?I. Divergent:
This boundary occurs when two plates separate and molten material rises from the mantle creating a new crust.
The hot material creates a new seabed between the separating plates, expanding the sea bottom.
II. Convergent.
Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one.
In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices.
The thicker and older plate subduces under the other plate.
III. Transforming.
The plates slide laterally with each other, and they are usually called faults.
It is associated, in general, with the oceanic ridge, although it might also occur in the continental plate.
No rocky material is either destroyed or formed.
When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur.
The movement breaks the crust and originates pronounced fractures.

Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. A scheme of blood circulation of reptiles except for birds. The reptiles have a three-chambered heart that consists of two atria and one ventricle with an incomplete septum. There are two circuits: pulmonary and systemic. In the pulmonary circuit, the blood from the right ventricle is pumped in to lung capillaries and returned to the left atria. In the systemic circuit, the blood is pumped from the left ventricle to the systemic capillaries via the left systemic aorta and is then returned to the right atria. There is also one vessel going from the right ventricle to the aorta right before it branches to smaller arteries. This vessel carries mixed blood. All blood on the right side of the circuits is venous and all blood on the left side is arterial. Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart. The three-chambered heart is inferior to the four-chambered hearts of birds and mammals, limiting the evolutionary success of amphibians and nonbird reptiles. Pulmonary and systemic blood fully mixes in the ventricle of a three-chambered heart.
Answer:
The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart.
Explanation:
In Anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
I. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
II. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
All amphibians and reptiles except for crocodiles (having four-chambered heart) have three-chambered hearts, which typically comprises of a partially divided ventricle and two atria.
Hence, the correct statement about the three-chambered hearts of amphibians and nonbird reptiles is that, the three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart due to the partially divided ventricle.

Once anything passes through the event horizon, from the perspective of that
object, nothing would change.
True or false
Answer:
True
Explanation:
The event horizon of a black hole is where gravity is such that not even light can escape. This is also the point I understand that according to Einstein time dilation will be infinite for a far-away-observer.
The statement "once anything passes through the event horizon, from the perspective of that object, nothing would change" is true.
What is horizon?The horizon would be the line that appears to divide a celestial body's ground from its own sky when observed by an observer standing on or close to the body's surface.
What is event?An event would be the collection of results from an experiment.
Therefore, the statement "once anything passes through the event horizon, from the perspective of that object, nothing would change" is true.

Describe an adaptation to a plant's life cycle and explain how this adaptation helps the plant survive. Source StylesNormal
Answer:
The adaptation of a plant in an environment ( for example,desert) depends on the structural parts of the plant which enables it to complete it's life cycle.
Explanation:
Plants are found in different types of environment. They need to possess and show some features that will enable them to live successfully and reproduce in that particular environment. Such features may be structural, functional or behavioural which are known as ADAPTATIONS.
Furthermore, in environment where there is scarcity of water supply, plants known as xerophytes can survive or thrive. They show the following adaptations:
--> well developed roots: the roots grow down to great depths if necessary and branch extensively in order to absorb water from as large an area as possible.
--> presence of swollen stems: These stems contains water storage cells which are called succulents. They help the plant withstand long period of drought.
--> Reduced leaves: This helps in reducing water loss from leaves through transpiration. For example in plants like the cacti, the leaves are reduced to spines.
Therefore, these structures helps the plant survive in its present environment.
