Answer:

1. Animals may to environmental stimuli through behaviors that include hibernation, migration, defense, and courtship. As a result of cold, winter weather some animals will hibernate. Examples of hibernating animals maybe ants, snakes, black bears, beavers, and ground squirrels.

2. Plants grow towards the light. Plant leaves bud and seeds germinate when the temperature is right. Their roots and stems grow in certain directions in response to the pull of gravity.

Answer:

a) For example, a cat may see a saucer of milk. Information from

the cat’s eyes travels along nerve cells to the brain, where the brain

processes the information. If the brain decides it wants the milk,

the brain sends a signal to the muscles in the cat’s limbs, and the cat

moves to the saucer of milk and drinks it

Explanation:

b) For example,

specialized cells in the leaves of trees detect the decrease in sunlight

as winter approaches. Chloroplasts then reduce production of green

chlorophyll. As existing chlorophyll is broken down, other coloured

particles are revealed, creating the beautiful red- and orange-coloured

leaves we see during autumn. Th e leaves eventually die and fall off . In

the spring, increased sunlight and warmer temperatures promote the

production of new leaves containing large amounts of chlorophyll, and

the green colour returns to the leaves.

Which of the following clades is most likely to survive a series of catastrophic events over time? (1 point)

marishachu [46]

The correct options are as follows:
1. D.
<span>A clade refers to a group of organisms that are made up of evolutionary descendants that originated from a common ancestor. A clade that will survive a series of catastrophic events must be one that is made up of distantly related and diverse species. This is because, those species will have different type of adaptability capacity and will be able to adapt in different ways to the catastrophic events. Due to the differences in their ability to adapt, some of the specie will survive the catastrophic events even if others are wipe out.

2. B.
The mass extinction of one specie usually creates space for another new specie to survive. The new specie that survive the old one may possess the ability to adapt to the event that wipe out the former set of living organisms and thus, the new specie will be able to occupy and reproduce in their new space. Mass extinction is said to occur when the whole population of living organism living in an ecosystem are wipe out as a result of unfavorable conditions.

3. B.
Convergent evolution refers to the independent evolution of similar features in species that arise from different lineages. The species involved usually evolve these traits as a result of having to adapt to similar environments. Convergent evolution usually result in evolution of analogous structures, that is, structures that have similar forms or functions but which are not present in the last common ancestors of the species.

4. C.
In evolution, gradualism refers to theory that states that evolution occurs slowly and gradually, thus, large changes in evolution are actually product of small changes that occur over a long period of time. The theory of gradualism was originally proposed by James Hutton in 1795.

5. C.
Mass extinction refers to the wiping out of a a large number of species within a very short time. Mass extinction can occur as a result of severe unfavorable conditions that all the species in an ecosystem can not adapt to. An instance of this is a drastic decrease in global temperature after several massive volcanic eruptions.</span>

To help explain surface tension, use a single water molecule in the template, and draw arrows representing the possible location

kramer

Answer:

The correct representation is attached with the explanation.

Explanation:

In this representation of the surface tension, blue arrows between green water molecules are the possible molecules that can be used as the location for forming hydrogen bonds by a single molecule. Surface tension is the tendency of a liquid surface strectch to neighbouring molecules or ability to shrink in minimum surface area possible. Hydrogen bonds is an intermolecular force or interaction responsible for the surface are of liquide molecules. This bonds is towards every direction where the similar molecule present.

musickatia [10]

The observed distribution of alleles into gametes is an illustration of Mendel’s law of segregation and independent assortment.

Mendel's law of independent assortment - the alleles a gamete receives get sorted into gametes independently of one another (one gene does not influence the allele received for another gene).

Mendel’s law of segregation - each gamete receives one gene copy selected randomly.
