hybrid
purebred
dominant allele
Answer:
I believe it's a dominant allele
Explanation:
Recessive allele means one is present... A hybrid is the result of two different breeds breeding. A purebred is an organism that always passes down the same genetic makeup.

Which process releases the highest amount of energy?
Answer:
glycolysis
Explanation:
In the process of glycolysis only 2 molecules of ATP are produced. Maximum energy is released, when the reduced coenzymes produced in the process of Krebs cycle are oxidised in the process of oxidative phosphorylation in electron transport chain.
The phase of mitosis that is characterized by the disappearance of the nuclear membrane is
Answer:
Prometaphase (late prophase)
Explanation:
Mitosis is the kind of cell division in which two genetically identical copies of a cell is formed from a cell. Mitosis comprises of stages which include prophase, metaphase, anaphase and telophase. Each phase is characterized by specific occurrences that all work together to achieve the main goal of forming two daughter cells.
According to this question, PROPHASE stage is the stage characterized by the condensation of chromatids into chromosomes, the disappearance of nucleolus and BREAKDOWN of NUCLEAR MEMBRANE.

1. What is a convection current?
2. How do thermometers work?
Answer:
1.a current in a fluid that results from convection.
2.measures temperature through a glass tube sealed with mercury that expands or contracts as the temperature rises or falls.
Explanation:
Answer:
1.A convection current is a process that involves the movement of energy from one place to another. It is also called convection heat transfer. What is the reason that makes you feel hotter when placing hands above a campfire or when sitting next to it? Or, why is the movement of liquid so rapid when water is boiled in a pot? These things happen as a result of the Convection Currents.
Explanation:
2. A thermometer measures temperature through a glass tube sealed with mercury that expands or contracts as the temperature rises or falls. ... As temperatures rise, the mercury-filled bulb expands into the capillary tube. Its rate of expansion is calibrated on the glass scale.

What is the main reason to put a telescope in space?
A.
It is much closer to the stars.
B.
It can receive star light that cannot reach Earth.
C.
Light reaching it is not affected by the movement of air.
D.
It can detect objects behind the moon.
Answer: D
Explanation:
The main reason we put telescopes into space is to get around the Earth's atmosphere so that we can get a clearer view of the planets, stars, and galaxies that we are studying. Our atmosphere acts like a protective blanket letting only some light through while blocking others.

The Minimal Chromosome To enable it to be transmitted intact from one cell generation to the next, the linear DNA molecule of a eukaryotic chromosome must have appropriate nucleotide sequences making up three special kinds of regions: origins of replication (at least one), a centromere, and two telomeres. What would happen if such a chromosomal DNA molecule somehow lost: a) all of its origins of replication
Answer:
The chromosome wouldn’t be able to replicate
Explanation:
Without an origin of replication, the chromosome could not be copied prior to mitosis.
QUESTION 1
Which of the following statements are true of arteries and veins? (Read carefully and select all of the correct statements.)
A. Venous anastomoses ensure that oxygenated blood will get to tissues.
B. The endothelium of both arteries and veins contributes to the prevention of abnormal clotting.
C. The smooth muscle layer of veins is thicker than that of arteries because veins are farther from the heart.
OD. Only veins have valves, which keep the blood moving between heartbeats.
E. The fibrous connective tissue layer of arteries is relatively thin because the blood is moving fast.
OF Arterial anastomoses ensure that blood will be able to return to the heart.
Answer: B, D
Explanation:
Is this a Med School K Question? The endothelial lining of blood vessels have many functions, including, preventing clotting. Veins carry blood that has very low pressure and have valves to control the one-way flow of blood. The rest are false. Only the pulmonary vein carries oxygenated blood. Arteries have more smooth muscles than veins. The anastomoses are present to act as alternative pathways to reach cells.

Which protein is damaged at the nerve endings during mercury toxicity
a. keratin
b. tubulin
c. pilin
Answer:
b. tubulin
Explanation:
Tubulin is a superfamily of proteins that make up microtubules who have many functions including intracellular trasport of neuron's vescicles
Tubulin protein is damaged at the nerve endings during mercury toxicity.
What do you mean by Mercury Toxicity?Mercury toxicity occurs when an individual is highly exposed to mercury.
The inhalation of mercury vapor can produce harmful effects on the nervous, digestive and immune systems, lungs, and kidneys, and may be fatal. This is considered as one of the severe toxicity that a person suffers.
Tubulin proteins are a very important class of proteins that helps in the formation of microtubules that have numerous functions in our body including the cytoskeletal arrangement of cells, intracellular transport of neuronal vesicles. And when a person suffers from mercury toxicity, such proteins are damaged and result in improper conduction of nerve impulses.
Therefore, Tubulin protein is damaged at the nerve endings during mercury toxicity.

Answer:
They all have a beating heart, and a brain
Explanation:
Beating the heart and a brain is the two characteristics that all these animal shares frog, buck, doves, lizard, and dragonflies.
What are the different characteristics of animals?Frogs are cold-blooded animals and are classified into the class of amphibians, they are vertebrate animals with backbones.
The lizard was included in the class reptilia, they are creeping and burrowing terrestrial animals situated on the land, and also have scales on their body. Similar to the frog, they are also cold-blooded animals having a backbone.
The major classification of the animals is done by the presence of a backbone, which differentiates them in vertebrates and invertebrates.
Therefore, in the given question all the animals share common feature of having a heart and brain.

7. Apply: Look carefully at the picture below and you will see an insect called a
katydid. Katydids evolved from grasshoppers through natural selection. Use
what you have learned to explain how this could have happened.
Answer: This description is an example of camouflage adaptations.
Explanation:
The grasshoppers are the insects which feed on plant parts and they are able to change their color with respect to their surrounding environment. For example, if they are living on the brown tree trunk they change their color to brown and on the green grass or green leaves they change to green to remain undetected by the predators. This way they are able to camouflage their predators this adaptation allows their survival in their environment with due course of natural selection. The phenotypic trait that is grasshopper is able to change its color increases the chances of survival of the grasshopper. Kaytids have evolved from grasshoppers means they have camouflage traits as that in parent grasshopper species. They have structure which blends with surrounding environment, that is they have wings that mimic that of pattern of leaf venation, also when they change the color to brown the shape of the body appears to be as that of stem. This structural adaptation help them to camouflage their predators.
