Explain why it makes sense that the levels of estrogen and progesterone are low in blood of a female during menstruation
PLS HELP ! URGENTTT
I'LL GIVE BRAINLY
Answer:
At the beginning of the follicular phase, the lining of the uterus (endometrium) is thick with fluids and nutrients designed to nourish an embryo. If no egg has been fertilized, estrogen and progesterone levels are low. As a result, the top layers of the endometrium are shed, and menstrual bleeding occurs.

A group of students is studying the types of plants that grow in a meadow next to their school. The meadow is mowed regularly, but it does not get any water other than rainfall. The meadow has several kinds of plants that are typically found in a grassland ecosystem. The plants include grass and clover. But there aren't any trees. The meadow has insects, including ants. Earthworms live in the soil. Garter snakes and mice also live in the meadow.
Answer:
Plowing cut tallgrass root systems and interrupted reproduction. Drainage changed the soil's water content, and soil erosion lost soil.
why is the ocean temperature near Christchurch change in El Niño years and how does it affect the air temperature there.
Answer:
Why the ocean near Christchurch is a different temperature than we'd expect for its latitude (distance from the equator). Water moving from the equator is warmer than would be expected based on latitude, and so is warmer than the air it passes.

Answer:
A. Mitochondrion
B. Cytoplasm
C. Nucleus
D. Chloroplast
Explanation:
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions
The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.
Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth.

Daily Biology Question! :)
Answer:
increasing[1], higher[2], space[3], food[4], climate change[5].
Explanation:
Because global temperatures are increasing[1], some species are seeking out higher[2] elevations in the Himalayas to colonize. Scientists were worried that these organisms would not have enough space[3] to live, but they have found that there is adequate food[4] at higher elevations. This movement may help these organisms survive the effects of climate change[5].
(Although am positive about 1, 2 and 5, you will need to double check 3 and 4. What I can tell you is that I don't think lifespan has to do with 3 or 4. I chose space and food simply due to the thought that more species moving to higher elevations allows for less space to live, but more prey to be hunted easier.)

3 benefits and 2 limitations for each, have till wednesday, so take ur time.
Answer:
BENEFITS:
The Descriptive investigation is used to describe a natural system when nothing or very little is known about the system. Like observing a new specimen in the microscope and describing it by observing the specimen.
A comparative analysis is used to compare two or more variable in nature by collecting data like observing the different colors of the rocks. It provides the data to show the similarity and dissimilarity of the population.
The Experimental investigation is used where experiments are performed to test and answer the scientific questions. The advantage is that data can be used as evidence for future research.
LIMITATIONS:
descriptive method of investigation
It cannot be used to correct variable or be used to determine causes and effect of the problem
experimental method of investigation
It might create an artificial situation that do not always represent the real life situation
comparative method of investigation
It is not easy to control other variables that might influence the study

What did Mendel's cross-pollination of pea plants prove?
A. Inherited factors combine in offspring to create entirely new characteristics.
B. Each parent only passes on one-half of its hereditary factors to each offspring.
C. There is no such thing as a true-breeding plant; they all have hidden factors.
D. It takes four generations of offspring to identify the parents' factors.
Answer:
B. Each parent only passes on one-half of its hereditary factors to each offspring.
Explanation:
Pea plants have both male and female reproductive organs. As a result, they can either self-pollinate themselves or cross-pollinate with another plant. In Mendel's experiments, he was able to cross-pollinate purebred plants with particular traits and observe the outcome over many generations.
As a little fun fact; as we know, both human parents have 46 chromosomes, and when reproduction occurs, they both give half of their chromosomes (23) to their offspring!

When relative humidity is 100%, the two thermometers register the same temperature. However, at 50% humidity, the wet bulb thermometer registers a lower temperature than the dry bulb thermometer. Why do you think the spinning motion cools the wet bulb thermometer when there is less humidity in the air?
Humidity likes to hold onto heat. The less humidity in the air the more the heat can be dissipated.
What do you mean by humidity?Humidity is the amount of water vapor in the air. If there is a lot of water vapor in the air, the humidity will be high. The higher the humidity, the wetter it feels outside. On the weather reports, humidity is usually explained as relative humidity.
Humidity is the measure of the level of moisture vapor suspended in the air around you. Although you can't see it, it's still there. The ideal relative humidity for health and comfort is somewhere between 30-50% humidity.
When the humidity level increases along with temperature, it's harder for the moisture to dry, and you feel warmer. When the air indoors is 75 degrees and the humidity is 30 percent, the air actually feels like 73 degrees.

Explanation:Adaptations occur when the genes of an organism change over time, usually due to external factors.
Beneficial Adaptation
Not all adaptation helps; as stated above adaptations can occur with any genetic mutation, even if it is not beneficial. That being said, beneficial adaptation helps an organism survive and reproduce, so helpful adaptations are the most likely to be passed on. Organisms that have harmful adaptations tend to have fewer offspring, meaning the adaptation does not pass on to the rest of the population.
If an adaptation decreases an organism's ability to survive or reproduce, then it is considered harmful. A beneficial adaptation must improve the life of an organism.
Camoflague
Camoflague allows an organism to hide from other living things, either to hunt or hide from predators. For these reasons, camouflage is considered beneficial. Specifically, butterflies use camouflage to hide and escape from predators that would eat them. This means that camouflage increases the life span of a butterfly. Thus, it must be a beneficial adaptation.

Give three ways that photosynthesis and respiration are dependent on one another.
Answer:
Both processes use and produce ATP in reactions that are carried out on membranes and are controlled by enzymes. Photosynthesis and respiration both involve cycles of reactions, involving redox reactions. The processes both use the same coenzymes, such as NAD and NADP.
Explanation:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
Nah i can give u one tho
Answer:
products of one systeme are the reactants of the other!
Explanation:
The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.
