Answer:
Not all animals use the same routes or excrete their wastes the same way humans do. Excretion applies to metabolic waste products that cross a plasma membrane.
The excretory system works with the respiratory, endocrine, urinary and digestive system. It works with the respiratory system because it helps the lungs get rid of carbon dioxide and water vapors. It works with the digestive system to help get rid of wastes that you eat through the anus.

Answer: dna replication happens in interphase before the mitosis
Explanation: During interphase the cell’s DNA inside the nucleus replicates forming two strands of DNA or chromosomes. In the interphase the DNA replicates in the S phase. Don’t confuse with G1 since in G1, which comes before S phase, replicates the cellular contents needed for this process
How do the densities of the planets support the Nebular Theory?
Answer:
The solar nebula theory explains that planets are formed by solid bits of matter. What that matter is entirely dependent on the gas and substances available.
Explanation:
which type of feature of Earth's crust does the diagram show (A) reverse fault (B) anticline (C) normal fault (D) syncline
its enviromental science
The figure illustrates the anticline of the earth's crust.
The correct option is B.
Anticline definition:A structural trap called an anticline is created when rock layers are folded into the shape of an arch. In an anticlinal trap, the rock layers were initially horizontally stacked until earth movement caused them to fold into such an arch-like structure known as an anticline.
What distinguishes an anticline?Rock formations called anticlines are folded structures with upward convex shapes. This means either anticline resemble a lowercase "n" or an uppercase "A" (remembering the shape of an anticline is as simple as saying "A is for Anticline"). They originate from horizontal and rather flat rock layers.
What is the crust of Earth?The outermost layer of a terrestrial planet is referred to as its "crust." The older, heavier continental crust and the denser, younger oceanic crust make up the majority of the Earth's crust. Plate tectonics provides information about the dynamic geology of the Earth's crust.

Alex is studying a population of fifty organisms that belong to the same species. Some of the organisms have dark spots, some have light spots, some have no spots, and some have stripes.
How does this species most likely reproduce?
Answer:
Sexual reproduction
Explanation:
There is a significant amount of genetic variation (diversity) here. Asexual reproduction results in little to no diversity, so we can assume this species reproduces sexually. Hope it helps :)
A cup is surrounded by air in room temperature
Describe the energy transfer between the water and air if the system is at equilibrium
A.Energy is transfers from air to the water
B. Energy transfers from water to the air
C. Energy transfers back and forth between air and water
D.None of the above
The energy transfer between the water and air if the system is at equilibrium does not carry any transfer of energy. So, the correct option is D.
What do you mean by Equilibrium state?Equilibrium may be defined as a condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs.
When the system is at equilibrium, the energy transfer between water and air surrounding the cup does not take place. It will only take place when there is a difference between the concentration of two solutions or objects.
Therefore, the energy transfer between the water and air if the system is at equilibrium does not carry any transfer of energy.

Which mutation scenario will always lead to natural selection?(1 point) A. a mutation causes a specific advantage within the population B. a mutation causes an inactivated gene to be reactivated C. a mutation causes a specific variation within the population D. a mutation causes a gene to become inactivated
A mutation scenario that will lead to natural selection is one that causes a specific variation within the population. Thus, the correct option for this question is C.
What is Mutation?A mutation may be defined as a type of process that significantly involves sudden, stable, and inheritable changes in the genetic material of an organism. The organism that undergoes mutation is called a mutant. The agent of mutation is called mutagen.
According to the context of this question, the process of mutation never causes a positive influence on the organisms, but with respect to time organisms become adapted or habitual.
A Mutation may be random and spontaneous so, it does not always involve an inactivated gene being reactivated. It sometimes involves the introduction of a new gene that facilitates specific functions.
Therefore, a mutation causes a specific variation within the population is a mutation scenario that will lead to natural selection. Thus, the correct option for this question is C.

The formation of a new community on land that has never had organisms grow on it before is known as
Secondary succession
Rebuilding
Biomagnification
Primary succession
Answer: Primary succession
Explanation:
The formation of a new community on land that has never had organisms grow on it before is referred to as the primary succession.
Primary succession takes place when there is no ecosystem that has existed before. It should be noted that the primary ecosystem is a slow process due to the fact that it starts on bare rock. This then provides a habitat which can be colonized. An example of primary succession is when there is eruption of volcanoes.
Describe the advantage of broad-leaved trees losing their leaves as winter sets in and the advantage of needle-leaved trees keeping their leaves if they are in poor soil
Answer:
The advantage of shedding broad leaves in the winter is to conserve the energy that needs to expand in order to provide heat to each part of the plant including leaves as in winters it becomes very dry and cold. If they do not shed their leaves they have to spend more energy to spend energy on leaves.
Needles like leaves have a thick cuticle layer that prevents from losing water in dry conditions or conditions with a limited amount of water in the soil. These leaves also help in photosynthesis by capturing more sunlight as they have a larger surface area. These adaptions can live in poor soil, rain and snowy conditions.

Meanwhile the ovary itself releases a hormone called estrogen which causes the uterine lining to increase in thickness.The uterine lining becomes thicker so that the fertilized egg can attach to it
Answer:
Meanwhile, the ovary itself releases a hormone called estrogen which causes the uterine lining to increase in thickness. The uterine lining becomes thicker so that the fertilized egg can attach to it. It is correct.
Explanation:
The hypothalamus, which is in the brain, releases a hormone called Gonadotrophin Release Hormone (GnRH). GnRH travels to the hypophysis, which is a gland located in the lower part of the skull. The GnRH makes the hypophysis release a hormone called Follicle Stimulant Hormone (FSH). This hormone travels to the ovaries, making it release estrogen. This hormone is in high concentrations during the 4th or 6th day of the cycle up to the 14th day, which is when ovulation happens. Estrogens make the endometrium, which is the outer layer of the uterus, grow making it thicker to prepare itself to attach the fertilized egg and provide to it the necessary nutrients to grow.
If the fertilization does not happen, the thickened endometrium will be expelled from the uterus some days later during menstruation.
In females, the uterine lining is at the site of fertilized egg attachment. The attachment of the fertilized egg makes the lining thicker.
What is the role of estrogen in uterine lining shedding?The estrogen hormone is produced by the ovaries of females. The hormonal cycle with rising, estrogen, and progression causes the menstrual cycle.
The non-fertilized egg triggers the release of estrogen, and the uterine line sheds off.
However, the fertilization of the egg results in a decreased signal of estrogen in the female body, and the uterine lining becomes thick without shedding.
Thus, the statement about the thickening of the uterine lining with the fertilization of the egg is correct.

Answer:
Book lungs are within small openings in the abdomen of the arachnid. The book lungs themselves consist of a series of haemolymph filled plate-like structures. Between the plates there is an air space and this allows air to circulate around the plates. Gaseous exchange then occurs through the surface of the plates.
