Answer:
PERICARDIUM MEMBRANE
The pericardium acts as mechanical protection for the heart and big vessels, and a lubrication to reduce friction between the heart and the surrounding structures. A very important role in all aspects of pericardial functions is played by mesothelial cells.
Our heart is surrounded by a double-layered membrane, called the pericardium or pericardial sac. This membrane keeps your heart in place in your chest cavity, restricts the expansion of your heart when your blood volume increases, and helps to protect your heart.
PERICARDIUM FLUID
Pericardial fluid is the serous fluid secreted by the serous layer of the pericardium into the pericardial cavity. ... This serous layer has two membranes which enclose the pericardial cavity into which is secreted the pericardial fluid.
If you breathed in a lot of chlorine at the pool, which of your cells would be affected? If an embryo were exposed to chlorine, which of his cells would be affected?
Answer:
I HATE KEYONNN\
Explanation:
If a lot of chlorine is breathed in, then it would harm the lungs' cells, especially the cells of the airways, the pseudostratified epithelial cells. It harms the different organs of developing embryos as it depends on the mother.
What is breathing?Breathing is the process of taking the oxygen inside the lungs from the atmosphere and releasing the carbon dioxide into the atmosphere. If a large amount of chlorine is taken, it will affect the cells in the airways.
Long-term inhalation of such gases causes lung problems such as acute lung disorder, asthma, pulmonary pneumonia, and so on. If such a condition arises, then it would be very difficult to provide proper oxygen to the body, and many other cellular activities would be affected.
In the case of developing embryos, it depends on the maternal supply. If the maternal blood is toxicated with chlorine, then it will supply the baby, and the developing baby organs will be affected. There are many disorders such as improper development of the brain, lungs, bones, etc. It will affect the embryo's cognitive capacity too.
Hence, a lot of chlorine affects the lungs the most when breathed.

A. 1. Embryological development is very similar for many animals so it would differ a lot from the DNA.
2. embryological evidence is a poor substitute for DNA evidence because of it's almost universal progression. It would be more difficult to see difference in embryos vs via DNA
D. Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. Like the arthralgus of a whale that looks very similar to a terrestrial mammals tells us that the whale evolved from land mammals
C. Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.

Some students investigated the effect of light intensity on the rate of photosynthesis.
They used the apparatus shown in Figure 1.
Figure 1
The students:
- placed the lamp 10 cm from the pondweed
- counted the number of bubbles of gas released from the pondweed in 1 minute
- repeated this for different distances between the lamp and the pondweed.
The lamp gives out heat as well as light.
What could the students do to make sure that heat from the lamp did not affect the rate of photosynthesis?
The student can do a couple of things to make sure that the heat from the lamp did not affect the rate of photosynthesis. These include:
Using a heat screen that light can pass through easily.Using Light Emission Diode in the place of the bulb.Using low energy bulb that will generate very little to no heat.Adding a water bath will ensure that the heat is absorbed by the water in the bath instead of heating the water in the test tube directly.Using any of the above will greatly minimize or totally eliminate the heat that will get to the plant and hence, will have no effect on the rate of photosynthesis.

What are two reasons why insects have been so successful at filling niches and adaptively radiating into so many different species?
Answer:
The ability to flyThe quinine exoskeletonExplanation:
The reason why insects are so successful in diversifying and adapting to different environments is closely related to their morphological and physiological adaptations.
In general, and compared with other groups, insects are small-sized. This characteristic also turns to be important and advantageous. Being small helps them find refuge in any place, escaping from predators, and as they are small they do not need too much food to survive.
Insects have a light and resistant exoskeleton made of chitin, a nitrogenated polysaccharide. This structure turns to be very important because it is impermeable to water, which helps the insect to avoid dehydration, helping the invertebrate to inhabit many different kinds of habitats. Also, the exoskeleton protects the arthropod from toxic substances and their natural enemies attacks, such as predators and pathogens
Insects are the only invertebrate with wings. Flying capacity is probably the most important adaptation that helped insects in their dispersion process to new areas. Being able to fly allows them to move huge distances looking for food, refuge, or mate. However, during evolution, some groups have lost the wings or have reduced their flying capacity.
The short life cycles, and their numerous litters, also helped them in their diversifying process.
The San Andreas fault is a transform fault. The map below shows a student's approximation of where the fault line crosses through the United States. Students were asked to make maps predicting which way land would most likely move over thousands of year.
Answer: Movement along fault line
Explanation:
Here's the remainder of the question:
Which map best predicts the likely movement of land along the fault line over thousands of years?
A transform fault is simply refered to a as a fault that occurs along the plate boundary such that the motion in such case is horizontal and ends when there's a connection with another plate boundary.
Based on the question, the map that best predicts the likely movement of land along the fault line over thousands of years will be a movement along fault line.
If scientists can inject human genes into a mouse, what does that tell you about the structure of DNA?
Answer:
Though humans and mouse looks very different from each other but they have lot of similarity in their genes.
If a mouse is injected with human genes, it tell that how the DNA structure in mouse and humans are similar and genes carry out related functions.
When the human gene will inject into mouse, if the genes functions properly and do not show any alteration in function, it means DNA structure is similar in both organisms.

Byron is observing organisms that are living in a patch of soil. He makes the following claim.
"I have observed 40 individual organisms. They are classified into 3 species, 1 phylum, and 2 kingdoms."
Which is the most accurate evaluation of Byron's statement?
A. The statement could be accurate because Byron organized the taxa correctly.
В.The statement cannot be accurate because 40 is much greater than 3 + 1 + 2.
C. The statement cannot be accurate because one phylum must be grouped into one kingdom.
D. The statement cannot be accurate because 3 species must be grouped into 3 phyla.
Answer:
The correct answer is - option C.
Explanation:
In this statement, he explained that there are 40 organisms that are comprised in the 3 species,1 phylum, and 2 kingdoms. It is not accurate as one phylum can not be placed in two distinct kingdoms.
A single phylum can have more than one species and one species also have hundreds and thousands of organisms. The phylum is lower taxa than the kingdom in taxanomy.

What do the phase changes (condensation, evaporation, crystallization) in the water cycle have in common?
Change in thermal energy from the Sun is the common factor during the phase changes ( condensation, evaporation, crystallization) in the water cycle.
What is Water Cycle ?Water cycle is the continuous movement of water between Earth and atmosphere. It is also known as Hydrological cycle. Water Cycle occurs in three phases i.e. Solid , Liquid and Gas. This cycle never stops, it doesn't have a beginning or an end. It's like a big circle.
Liquid water evaporates into water vapour which condense to form cloud and precipitates back to earth in the form of rain or snow. It is a simple circular cycle of evaporation, condensation and precipitation.
Water vapour is the primary form of atmospheric moisture. Its storage is small, water vapour is extremely important in forming the moisture supply for dew, frost, fog,etc.
There are Five parts of the water cycle. They are
1. Evaporation
2. Transpiration
3. Condensation
4. Precipitation
5. Runoff.
Thus, change in thermal energy from the Sun is the common factor during the phase changes ( condensation, evaporation, crystallization) in the water cycle.

Que relação existe entre a concentração de iões K+ no interior das células guardas e a abertura dos estomas?
Answer:
Los iones K + tienen un gran efecto en la apertura de los estomas.
Explicación:
Existe una gran relación entre la concentración de iones K + dentro de las células de guarda y la apertura de los estomas porque la concentración de iones de K + aumenta la concentración osmótica dentro de la guarda. El agua entra en las células de guarda por endosmosis, lo que aumenta la turgencia. La presión de turgencia de las células protectoras aumenta debido a esta endosmosis y las células protectoras permiten que los estomas se abran, por lo que podemos decir que los iones K + tienen un gran efecto sobre la apertura de los estomas.
The graph shows the changing levels of hormones during menstruation and ovulation. What happens to hormone levels during ovulation, and why is this important?
Answer:
The estrogen level decreases during the ovulatory phase, and the progesterone level starts to increase. And it is important, because hormones that are being releazed stimulates the egg to move from the fallopian tube, which then leads to menstruation.
Explanation:
The ovulatory phase begins with a surge in luteinizing hormone and follicle-stimulating hormone levels. Luteinizing hormone stimulates egg release (ovulation), which usually occurs 16 to 32 hours after the surge begins.
Answer:
Hormone levels generally decrease.
