The theory of evolution has changed over time. Initially, Lamarck believed that organisms developed traits in response to a changing environment to improve their chances of survival. Later Darwin proposed that organisms that already possessed traits suitable to a changing environment were more likely to survive and reproduce.
Which of the following does not explain why the theory of evolution has changed?
A. Lamarck’s theory was discarded when new scientific information became available.
B. Darwin collected empirical evidence to support that organisms with favorable traits survived and reproduced.
C. The theory of evolution became a scientific law after much debate and confirmation in the scientific community.
D. Other scientists such as Peter and Rosemary Grant have collected additional empirical evidence that supports Darwin’s findings.

Genes and Proteins in Hemophilia
Genetic researchers at Bay Medical Company are working to improve treatments for hemophilia. Currently, they are investigating the possibilities of gene therapy, which involves changing a person’s genes so that that person no longer has hemophilia. In order to help Bay Medical Company with their research, read the passage below and then answer the question.
Genes are instructions for proteins. Your traits are determined by the kinds of proteins your body makes. For example, when you get a cut, clotting factor proteins connect to form scabs. People with hemophilia do not have a version of the gene with the right instructions for making clotting factor VIII protein. Without the right instructions, their cells can’t make the proteins needed to form scabs. Healthy people have at least one copy of the gene that provides the right instructions for making all of the clotting factor proteins.
If genetic researchers found a way to change a person’s genes, would they be able to cure hemophilia? Why or why not?

When rain changes to ice pellets what happens to the temperature?
Answers
Explanation:
When rain changes to ice pellets, the temperature at the surface usually drops. This is because the process of rain changing to ice pellets, also known as sleet or graupel, involves the raindrops passing through a layer of freezing air near the surface. As the raindrops fall through this layer of cold air, they freeze into ice pellets.
This process releases latent heat, which is the energy absorbed or released by a substance during a change in state. In this case, as the water droplets freeze into ice pellets, they release latent heat, which slightly warms the surrounding air. However, this warming effect is generally offset by the cooling effect of the freezing air near the surface, resulting in a net drop in temperature.
It's worth noting that the specific temperature change will depend on various factors, such as the temperature and humidity of the air mass, the intensity of the precipitation, and the duration of the sleet or graupel event. In some cases, the temperature drop may be relatively small, while in other cases, it may be more significant.
The temperature suddenly becomes colder.

A metal body of mass 81 g occupies a volume of 30 cm3. Identify the metal.
Answers
Answer:
Aluminum
Explanation:
The density of Aluminum is 2.7 g/cm3
We know the volume and mass of the unknown metal, as density is mass/volume: 81g/30cm3 = 2.7 g/cm3 which is the density of Aluminum :)
Given parameters:
Mass of metal = 81g
Volume of metal = 30cm³
Unknown:
Identity of the metal = ?
To find the identity of the metal, we must derive an intrinsic property from the give parameters which we can use to identify it.
This property is density.
Density is mass per unit volume of a substance. Every earth material has a unique value of density.
Density = \(\frac{Mass}{Volume}\)
If we find density, we look up a density table and identify the element.
Input the parameters and solve;
Density = \(\frac{81}{30}\) = 2.7g/cm³
The metal with a density value of 2.7g/cm³ is aluminium.

Answers
it’s melting
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

List 3 negative impacts does plastic pollution have on the ocean?
Answers
Ingestion
And suffocation
Answer:
Negative physical impact on marine life, chemical impact on the water, and transport of native species.
Explanation:
Negative physical impact on marine life:
Plastic can be dangerous to creatures living in the ocean. Marine animals can fatally swallow plastic, become entangled in it, and even become physically impaired for the rest of their life.
Chemical impact on the water:
Plastics carry chemicals such as PCBs and DDT that can invade the water and cause harm to marine ecosystems.
Transport of native species:
Plastic can carry organisms from one part of the ocean to a relatively remote area. By introducing new organisms to an ecosystem, the flow can be disrupted and result in major consequences.

Answers
Answer:
The best description of the likely impact of an invasive plant species on a warm ecosystem is:
The invasive plant species take over resources used by native plant species. Some plant species decrease in population, affecting the food source for consumers in the ecosystem.
Invasive plant species have the ability to outcompete native plant species for resources such as sunlight, water, and nutrients. This can lead to a decrease in the population of native plant species as they are unable to access sufficient resources to thrive. As a result, the food source for consumers in the ecosystem may be affected, leading to potential changes in the population dynamics of the consumer species.

gravitational force, tidal bulge
low tide, gravitational force
Answers
The gravitational force of the moon on the earth causes the tides to occur in the oceans and water bodies. Gravitational force and tidal bulge are the correct blanks.
What is the relationship between gravitational force and tidal bulge?The moon pulls and creates a force of gravity on the planet earth and causes bulges and tides of the oceans on the planet. The gravitational pull of the moon causes bulge formation, one towards the moon and another facing away from the moon in the oceans.
The bulge facing towards the moon has a stronger force while the bulge away from the moon has weak force. The gravity and the pull are more on Earth when the moon is near and earth is facing towards it.
Therefore, option C. gravitational force, tidal bulge is the correct blank.

Why do they have the greatest magnitude ?Magnets will only attract each other and therefore have a great magnitude if they are facing opposite poles. Pair 3 are therefore out because it has the same pole facing the other.
Magnitude of magnetic force will increase the closer the magnets are to each other. Seeing as Pair 1 has the lowest distance of 0. 3 cm, it means that Pair 1 would have the greatest magnitude.

Beth wrote the following description of the life cycle of non-flowering, seed-bearing plants. Read her description and find the mistake.
"Non-flowering, seed-bearing plants go through four major stages in their life cycles. The first stage is when the plant is a seed from a cone. The second stage is when the plant sprouts out of the seed and the cones begin to grow. The third stage is when the plant is a seedling. The fourth stage is when the plant is a bigger seedling."
What statement corrects the error in Beth's report?
There are five stages in the life cycle of non-flowering, seed-bearing plants, not four.
The first stage is when roots will grow out of the seed and down into the soil.
The third stage is when the plant sprouts out of the seed and the flower grows.
The fourth stage is when the plant is an adult plant growing leaves and cones which produce more seeds.
