Scientists have found ash in certain layers of sediment in an area in northern China. This is evidence that a volcano erupted in the area in the past. In the same sedimentary layers, fossils of dinosaurs, birds, and early mammals have been found. How can scientists best determine when the volcano erupted?
Scientists can find out when the volcano erupted by determining the age of the fossils in the ashy layers of sediment in area.
What is a Volcano?This is defined as a vent or opening where lava erupts on to the surface of the Earth.

Variation in offspring is important in maintaining genetic diversity within a population. Which of the answer choices indicates a mechanism of introducing genetic variation in a population? Select all that apply.
A) crossing over during meiosis
B) fertilization of an egg by a sperm
C) independent assortment during meiosis
D) mitosis producing two new daughter cells
E) binary fission resulting in two bacterial daughter cells
Answer:
The answer would be A, B, and C.
Explanation:
Since genes shuffle and assort randomly in meiosis, this is a cellular process that results in greater genetic diversity. Because haploid gametes form a diploid zygote in fertilization, this also increases genetic variation. However, binary fission and mitosis only result in daughter cells that are clones of the parent cell.
which of the following statement is true
a. friction makes an object slides
b. gravity pushes an object upward
c. force is needed to stop object
d. an object in motion will remain in motion.
The correct statement among the given answers is letter d. an object in motion will remain in motion.
WHY?In reality, object that is in motion (like a ball) will remain in motion unless it's stopped by something (a wall or any force).
This is stated in the first law of motion by Sir Isaac Newton -- an object in motion will remain in motion unless an outside force acted upon the object.
A synapse is the specific location where ____________ is functionally connected to either another neuron or ____________ . There are two types of synapses in the human body: chemical synapses and electrical synapses. Most synapses within the nervous system are ____________ synapses.
Synapse is the connection stablished between neurons or between neurons and effector cells. a) a neuron b) effector organ c) chemical.
What is a synapse?
Neurons transmit nervous impulses.
Every neuron forms connections with other neurons or with effector organs, such as the muscle. These connections are known as synapses.
Synapses can be either chemical or electrical. The most common one is the chemical synapses that involve the release of a substance known as a neurotransmitter.
During chemical synapses, when a presynaptic neuron sends information, it releases neurotransmitters. This event is done through exocytosis.
The neurotransmitter is a molecule that travels through the synaptic space forward to the other neuron or effector cell. Once the chemical reaches the postsynaptic membrane, it binds to its receptors.
This binding neurotransmitter-receptor produces excitatory postsynaptic potential, which is the depolarization of the postsynaptic cell.
Once the action potential is initiated, it spreads to the rest of the membrane, depolarizing it.
A synapse is the specific location where _a neuron_ is functionally connected to either another neuron or _an effector cell (i.e. muscle)_ . There are two types of synapses in the human body: chemical synapses and electrical synapses. Most synapses within the nervous system are __chemical__ synapses.

Convergent evolution is when a species evolved from a common ancestor.
True
False
Answer:
False
Explanation:
Convergent evolution is when two species with different ancestors evolve to have similar traits to do similar purposes. Ex: the structure of the arm of differnet mamals. They all do the same thing, and the general make up is the same, but mammals are in no way the same species.
Divergent evolution is the type of evolution that comes from species of the same ancestor, but thats when they evolve differently despite having the same ancestor to adapt to their enviroment (ex: bird beaks).

These proteins are called interferon because they interfer with the activities of viruses and prevents them from multiplying.
There are two type of interferon which are secreted by different cells they include:

Cross a female with normal color vision, but whose father was colorblind, with a man who has colorblindness. Tell the expected phenotypic ratio of the offspring
If a female with normal colour vision, but her father was colour blind crosses with the man who has colourblindness, the phenotypic ratio of the offspring is 50%.
What is Colorblindness?Colour blindness is linked to the X-chromosome defect. It is a condition in which a person is unable to see the colors or differences in colours or its abilities decreased. For example, he was unable to distinguish between the colour of traffic lights, colour of fruits or choosing clothes.
Colour blindness is to be present on all X chromosome within the individual have to be affected; so the man has only one X-chromosome and women have two, the chances of colour blindness is much more higher in men as compared to women.
In the above example due to genetic inheritance of the mother from her father, the chances of colour blindness in their child is 50% because each parent is a carrier having X chromosome.
In this case chances of inheriting colour blind X chromosome would be double as likely for female child because both mother and father are the carriers of X chromosome of colour blindness.
Thus, if a female with normal colour vision, but her father was colour blind crosses with the man who has colourblindness, the phenotypic ratio of the offspring is 50%.

The illustration below shows the wing structure of an insect. Line-drawing of insect wing, showing outline of wing and pattern of veins. The wing is narrow where it attaches to the body, gets wider, then gets narrow again, and has a rounded tip. Which of the following animals will most likely have a wing structure that is very similar to this insect’s wing structure?
A. An animal from the same class
B. An animal from the same genus
C. An animal from the same phylum
D. An animal from the same kingdom
An animal from the same class as the insect will most likely have a wing structure that is very similar to the insect's wing structure. Therefore, the correct statement is option A.
What are insect's wings consisting of?The class here is Insecta, which includes all insects. Insects are a diverse group of organisms having unique features, including wings. Insect wings consists of a thin, membranous layer supported by a network of veins.
The veins provide structure and strength to the wing and is a characteristic of the class Insecta. However, there is a large variation in insect wings, shapes, sizes, and patterns of veins, the basic structure is the same.
Insect wings are narrow where they attach to the body, get wider toward the middle of the wing, and then get narrow again at the tip, often with a rounded or pointed shape. This general shape and vein pattern is common to all insects with wings.
Therefore, the insects, which belong to the same class Insecta, will have similar wing structures to the insect in the illustration.
