Answer
If the uterine wall thickens
Explanation:
A,B,D, these are all things that happen on a daily to women and most of them still have good horomone levels
When the egg is not fertilized that causes a drop in female hormone levels. So, the correct option is D.
What are Female hormones?Sexuality and fertility are influenced by the three primary reproductive hormones are estrogen, testosterone, and progesterone. Pregnancy, puberty, menstruation, menopause, sex drive, sperm production, and other processes are all controlled by them. These hormones are made in the testes in males and ovaries in females.
The ovaries release the main female sex hormones. The ovary releases female gametes or eggs during ovulation. Following the discharge of the eggs, the ovary forms a corpus luteum, which secretes progesterone and oestrogen to prepare the uterine lining for a prospective pregnancy. The level of female hormones decreases when the egg is not fertilized.
Therefore, the correct option is D.

right answer gets brainliest!
Answer:
Cartilage
Explanation:
The flexible connective tissue shown in blue is cartilage.
Explanation:The flexible connective tissue in the shoulder joint is primarily cartilage. Cartilage is a tough and resilient tissue that covers the ends of bones where they meet in a joint, providing a smooth surface for low-friction movement. In the shoulder, it is found in the glenoid cavity of the scapula (shoulder blade) and the head of the humerus (upper arm bone).
This articular cartilage reduces friction and cushions the joint during various movements like arm rotation and lifting. While cartilage plays a crucial role in the shoulder joint's flexibility and function, it can be susceptible to wear and tear, leading to conditions like osteoarthritis.

Forever friend and helper,
Cammie:)
If the inner membrane of mitochondria is not folded, then it would have less energy due to a smaller area for cellular respiration to take place. The correct option is A.
What is mitochondria?Mitochondria are membrane-bound cell organelles that garner the majority of the chemical energy required to drive the biochemical reactions of the cell.
The mitochondrial energy is kept in a small molecule known as adenosine triphosphate i.e., ATP.
Several hundred to thousands of mitochondria are found in the fluid that covers the nucleus in each cell i.e., cytoplasm.
The mitochondria, also renowned as the powerhouses of the cell, produce the energy required for the cell's continued existence and function.
Mitochondria use a series of chemical reactions to convert glucose into an energy molecule known as adenosine triphosphate which is used to power various cellular processes.
If the inner membrane of the mitochondria is not folded, it will have less energy because there will be a smaller area for cellular respiration to occur.
Thus, the correct option is A.

The data shows that recently the shark population increased. How will the increase in the shark population affect the other populations? Be sure to explain whether the sea otter population, the sea star population, and the clam population will change, and why.
Answer:
If there is an increase in the shark population, then there will be a slight decrease in the other populations.
Explanation:
Based upon the three animals listed, the shark is at the top of the food chain. This means that the shark will eat the sea otter and see star, declaring their population will decrease.
An increase in shark population can have a ripple effect on other marine populations due to the interconnectivity of their food chain. For instance, sea otter population might decrease due to increased predation, leading to an increase in the sea star population and a potential decrease in clam population. However, environmental factors such as greenhouse gas emissions and ocean temperatures can also trigger shifts in marine populations.
Explanation:An increase in the shark population can significantly affect other marine populations. For instance, if sharks, who are predators at the top of the food chain, increase in number, they may increase predation on sea otters, a favorite food source, potentially decreasing the sea otter population. This, in turn, could increase the sea star population as sea otters often consume sea stars.
The trend might also increase populations of some other species like clams. If sea stars, which are predators of clams, increase due to a reduction in sea otters, then the clam population might decrease. However, if the increased shark population also reduces the number of seal (a clam predator), then the clam population might, in fact, increase.
Environmental factors such as increases in greenhouse gas emissions and fluctuations in ocean temperatures can also trigger shifts in marine populations. It's important to note that the interconnectedness of these marine populations means a change in one can have a ripple effect on the others.

Iridium is a substance found only in asteroids and other space objects. This graph shows the amount of Iridium found in different sediment layers of Earth. They are marked off into 17 sections representing time.
Iridium Levels graph shows Iridium levels in sediment layers. Beginning at sediment layer 1, iridium levels remain between 0 and 5, jumping to a level of 23 between layers 5 and 6, and decreasing to near starting levels at layers 14 through 17.
What most likely happened in sediment layer 5?
A massive volcano erupted, causing global warming and lava flow, which in turn caused mass extinction.
More iridium was produced by space objects and dumped by local factories.
A massive dust cloud formed, causing global cooling and a lack of sunshine. This in turn caused a lack of plants and a mass extinction.
Fewer impacts lead to a drop in iridium levels and a mass extinction caused by a lack of sunshine.
In sediment layer 5, more iridium was produced by space objects and dumped by local factories is likely to happened.
Sediment rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding.
Sediment rocks are formed on or near the Earth's surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering.

The increase in Iridium levels in sediment layer 5 is likely due to an asteroid impact because iridium is primarily found in asteroids.
Explanation:Based on the provided information, it is likely that the higher levels of iridium found between layers 5 and 6 are due to an asteroid impact. Iridium is a substance primarily found in asteroids and other space objects. An increase in iridium levels in a specific sediment layer would suggest an influx of material from space, such as an asteroid strike. Therefore, the spike in iridium does not align with the scenarios of a volcanic eruption, more iridium being produced locally or the formation of a dust cloud.

the life cycle of a white wagtail
The life cycle of a white wagtail starts from mating, laying of eggs, hatching, fledgling stage, and finally adulthood. As they mature, they develop distinctive markings and undergo annual migrations. The change of climate is vital for maintaining a constant body temperature and survival.
Explanation:The life cycle of a white wagtail, like other birds, begins with mating and the laying of eggs. The parents take care of the eggs, which will then hatch into hatchlings. The hatchlings, still dependent on their parents, continue to grow until they become fledglings, where they can nearly take care of themselves. Eventually, they will mature into adult wagtails capable of starting their own families.
During each stage of the life cycle, the white wagtails go through changes specific to their species. For instance, they develop distinctive feather colors as they mature and undergo annual migrations for suitable mates and habitats, similar to the American white pelican.
Migration is an important aspect of the life cycle of many bird species, including the white wagtail. During migration, they also adjust to warmer climates to maintain a constant body temperature which is crucial for their survival and ability to reproduce.

Insulin and glucagon work together to balance your blood sugar levels, keeping them in the narrow range that your body requires. These hormones are like the yin and yang of blood glucose maintenance. Read on to learn more about how they function and what can happen when they don’t work well.
You observe small bubbles of air on the underside of an underwater leaf.
Where could these air bubbles be coming from?
Answer:
This could possibly be caused by some sort of insect or some microscopic being on the leaf.
Explanation:
The air bubbles on the underside of an underwater leaf are likely produced by photosynthesis, where plants release oxygen as gas bubbles, and may also be associated with aquatic insects and spiders that create or carry air bubbles to breathe underwater.
Aquatic plants, like all plants, take in carbon dioxide and use sunlight to convert it into oxygen and glucose. The oxygen produced can be released as gas bubbles, which you see attached to the leaf. Similarly, some underwater creatures, such as aquatic insects or spiders, may carry or generate air bubbles for respiration. For example, diving bell spiders create air bubbles to help them breathe underwater by trapping a bubble that sticks to their hairy abdomens and taking it to their silk air tanks, also known as "diving bells". This adaptation allows them to stay submerged for extended periods.

B)Genetic variation among lizard limbs allowed for natural selection to occur.
C)The limbs were artificially selected because humans probably caused the flooding.
Answer:
B)Genetic variation among lizard limbs allowed for natural selection to occur.
Explanation:
Natural selection is the phenomenon in which creatures evolve as time goes on. This evolution occurs when the species experiences a certain natural challenge that it can adapt to. Lizards that had short legs died in the floods while the lucky longer legged lizards were able to pass on their genes to the next generation. This is Natural Selection in action.
Answer:
B
Explanation:
When the lizard go through natural selection, they evolve to the threat of flooding. Henceforth, they grow longer legs. The genes for longer legs will continuously be passed down to more and more generations.
