What are two different ways that
weathering can happen?
Chemically & Physically(mechanically)
erosion & physically (mechanically)
chemically & deposition
Answer:
Chemically & Physically(mechanically)
Explanation:
Weathering is the wearing away of rock found at the surface of the earth. There are different ways weathering can occur and they include;
1. Mechanical weathering: This is the breakdown of rock into bits or fragments. Physical factors such as water can lead to this breakdown. When water falls into the pores and cracks of rocks, pressure can be created that will eventually result in the breakdown of these rocks.
2. Chemical weathering: This type of weathering causes a change in the physical makeup of the rock. The new form of rock created is more prone to erosion. Temperature is factor that can speed up chemical weathering.
Explain the concept of 'natural selection' and what it really means. Specify what
mechanism actually causes the natural selection and why it occurs.
Answer:
Natural selection is a proccess that occurs when an oganism is to weak to survive against other predators in that environementIt has failed to find a suitable nihe and evolution will cause it to become extinct from that geographic area.
Natural selection is the theory behind evolution put forth by Charles Darwin. Given the scarcity of resources in nature, animals with heritable features that promote survival and reproduction will typically produce more offspring than their contemporaries, leading to an increase in the frequency of such traits across successive generations.
Why is natural selection important?Charles Darwin's theory of evolution is known as natural selection. Animals with heritable qualities that aid in survival and reproduction will often generate more offspring than their contemporaries due to the limited resources in nature, increasing the frequency of such traits through subsequent generations.
Favorable features are passed down across generations as a result of natural selection. Natural selection may result in speciation, the process by which one species gives rise to another that is utterly separate.
It is one of the mechanisms that propels evolution and contributes to the understanding of the variety of life on Earth.
Thus, this is the main concept of natural selection.

Explanation:
Connell’s results led him to conclude that Chthamalus’ realized niche is smaller than its fundamental niche because of interspecific competition with Balanus. But what if competitive exclusion were not the explanation? What if Chthamalus’ and Balanus’ respective niches were a result of niche differentiation instead? Niche differentiation occurs when two species with overlapping niches change over time in a way that reduces their niche overlap, and thus reduces their competition for resources.
Answer:
Both realized niche and fundamental niche are similar in size.
Explanation:
If Chthamalus’ and Balanus’ respective niches were a result of niche differentiation so we can say that Chthamalus’ realized niche is not smaller than its fundamental niche. It will be of the same size because of no interspecific competition with Balanus. The whole fundamental niche is considered the niche of the Chthamalus' alone due to no competition with Balanus' for resources present in the ecosystem.

Answer:
A. aneuploidy; trisomic
Explanation:
Down syndrome is probably the most common example of a chromosomal aneuploidy. It is trisomic because an extra copy of Chromosome 21 is made, also known as Trisomy 21.

Explanation:
Which part of the female reproductive system is highlighted below?
A. Fallopian tube
B. Ovary
C. Uterus
D. Cervix
Answer:
C. Uterus
Explanation:
Uterus is the female reproductive system.
What is Female reproductive system?The female reproductive system serves a number of purposes. It aids in sexual reproduction in addition to enabling sexual activity.
You make eggs using your ovaries. During ovulation, these eggs are subsequently moved to your fallopian tube where sperm fertilization may take place. The fertilized egg is then transferred to your uterus, where the lining of the uterus has expanded due to the typical hormones produced during your menstrual cycle, also known as your reproductive cycle.
The fertilized egg can implant into the thicker uterine lining once it's within your uterus and continue to grow there. Your menstrual period causes the uterine lining to shed if implantation doesn't occur.
Therefore, Uterus is the female reproductive system.

Explanation:
Although animal nervous systems differ in complexity, their nerve cells are still remarkably similar. true false
Answer:
TRUE
Explanation:
The nervous system only exists in animals. Neurons are the nerve cells that compose the nervous system.
The neuron´s principal function is to catch stimuli from the exterior convert them into nerve impulses that get transported to the control centers. These control centers interpret the signal and send an answer to the stimuli.
The control centers in invertebrates are ganglia, while the vertebrate´s control centers are the spinal medulla and the encephalon.
The signal transport occurs from cell to cell in inferior animals and through nerves in superior animals.
There is a progressive increase in the complexity of the nervous system. It evolved from primitive animals to the most superior ones. This evolution is especially noticeable in the development of the encephalon as the control center.
However, the basic nerve cell is very similar in all animals.

What is the function of Stomata?
Answer: Stomata, the small pores on the surfaces of leaves and stalks, regulate the flow of gases in and out of leaves and thus plants as a whole. Stomata are composed of a pair of specialized epidermal cells referred to as guard cells (Figure 3). Stomata regulate gas exchange between the plant and environment and control of water loss by changing the size of the stomatal pore.

6. When does the DNA in a cell replicate?
a. before cell division (mitosis or meiosis)
b. during cell division (mitosis or meiosis)
after cell division (mitosis or meiosis)
d. at random times throughout the cell's life cycle
Answer:
the answer is A before cell division (mitosis or meiosis)
Explanation:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

a. How similar DNA is between organisms
b. The length of the organism’s life
c. Where fossils are found
d. How similar the organisms were as embryos
Answer:c where fossils are found
Explanation:
Where fossils are found is not a line of evolutionary evidence supported by empirical evidence. Therefore, option C is correct.
What are fossils ?Any surviving remains, impression, or evidence of a once-living thing from a previous geological epoch is referred to as a fossil. Examples include exoskeletons, bones, shells, animal or microbe imprints in stone, items preserved in amber, hair, petrified wood, and DNA traces. The fossil record is the collection of all fossils.
Shells, bones, animal or microbe imprints in stone, exoskeletons, items preserved in amber, petrified wood, coal, hair, oil, and DNA traces are a few examples of fossils.
The majority of fossils are created when a living thing (such as an animal or plant) dies and is swiftly buried by sediment (such as mud, sand or volcanic ash).
