Answer:
Large amounts of water do have a big impact on the weather: indeed, it takes less energy to warm/cool land than water.
Therefore, places near large amounts of water tend to have smaller differences in temperature between summer and winter than places far from waters.
Hence, during winter in Puerto Rico, alongside the coast, the temperature will be higher than in the innermost parts of the island.

Match each type of lipid to its characteristics. Drag the items on the left to the correct location on the right. (photo attached)
phospholipid -> two fatty acids, a glycerol molecule, and a phosphate group
triglyceride -> three fatty acids and one glycerol molecule
steroid -> four fused rings
triglyceride -> forms saturated or unsaturated fats
phospholipid -> provides fluidity to the cell membrane
steroid -> present only in animal cells
I got you <33 and I see it perfectly ! :)
Both triglycerides and phospholipids contain a gylcerol backbone. Steriods contain fused rings and are only found in animals.
Phospholipids and triglycerides share a common structural feature in common and that is the presence of a glycerol backbone in the molecule. Glycerol is a three carbon compound. In a phospholipid, there are two fatty acids and a phosphate group attached to the carbon atoms. In a triglyceride, there are three fatty acids that attach to each of the carbon atoms.
Steriods are composed of fused rings and are found in animals. They play very important roles in the body. An example of a steroid is cholesterol.
Matching the items on the left and right of the image;
phospholipid - two fatty acids, a glycerol molecule, and a phosphate group/provides fluidity to the cell membrane
triglyceride - three fatty acids and one glycerol molecule/forms saturated or unsaturated fats
steroid- four fused rings/ present only in animal cells

Which causes a drop in female hormone levels?
the onset of the menstrual flow
if an egg is released from the ovary
if the uterine wall thickens
if the egg is not fertilized
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.

Moin took some soil and measured the concentration of nitrogenous compounds in it. He distributed the soil equally in two pots- P and Q which he placed in sunlight.
He planted 10 sunflower seeds in Pot P and allowed them to grow. He did not grow anything in the Pot Q.
After one month, he tested the concentration of nitrogenous compounds in both the pots.
What do you think was his observation?
Answer: The nitrogenous compounds in the Pot P will be depleted and the Nitrogenous compound in the Pot Q will have same amount of it.
Explanation:
Moin took soil and put into two pots. In one of the pot which he labelled P,planted sunflower seeds.
Whereas, the pot Q he left as it is with no plantation in it. The observation after few days will be that the level of nitrogen in the pot P will be less compared to the pot Q.
Nitrogen is one of the important micro nutrient which serves many important functions in the plant body. It is the main component of chlorophyll and is important in enzyme synthesis.
Hence, pot P will have its nitrogen consumed by the plant and pot Q will have nitrogen in its soil.

Habitat is a place in which organisms live, and niche is the way in which an organism fits into its habitat. Habitat is a group of organisms that live in an area, and niche is a specific species that lives in that area. Niche is a group of organisms that live in an area, and habitat is a specific species that lives in that area.
Answer:
Habitat is a place in which organisms live, and niche is the way in which an organism fits into its habitat
Habitat is a place in which organisms live, and niche is the way in which an organism fits into its habitat, hence option B is correct.
What is the habitat?An ecosystem's habitat and niche are critical components. They aid in explaining how an organism interacts with its surroundings, including biotic and abiotic elements.
Ecological interactions are the subject of research. There is a slight difference between the words “habitat” and “niche.”
Only after an ecology develops and niches are incorporated into it does a habitat become active (realized habitat). This process, known as habitat differentiation, is intricately linked to the existence of a healthy ecosystem.
Therefore, they inhabit different habitats, it is feasible for two animals to share the same niche (same function) within an ecosystem.

These beetles have a uniform distribution. In year 1, how many beetles are there per hectare? How many beetles per
hectare were there in the year the beetles reached carrying capacity? Round up or down to the nearest whole number, if
necessary.
Answer -
In year 1, the population was 11,500 spread over 115 hectares
In year 1, there were 100 beetles per hectare (11,500 beetles / 115 hectares).
In year 1, the beetle population exhibited a uniform distribution, meaning it was evenly spread across the area. The total population of 11,500 beetles was distributed over 115 hectares. To calculate the density, the total number of beetles was divided by the total hectare area, resulting in an average of 100 beetles per hectare. This indicates that, on average, there were 100 beetles within each hectare of the habitat in the first year.
As the population reached its carrying capacity, the density per hectare became more stable, providing insights into the ecological dynamics of the beetle population and its relationship with the surrounding environment. It's essential to consider ecological factors that may impact population distribution and density, contributing to a comprehensive understanding of the ecosystem.

the father's the one because he's the only one with the y chromosome hence if the sperm containing the y chromosome fertilises the ovum then the kid is a boy and if its the one with the x chromosome then its a girl
Answer:
In the XY sex-determination system, the female-provided ovum contributes an X chromosome and the male-provided sperm contributes either an X chromosome or a Y chromosome, resulting in female (XX) or male (XY) offspring, respectively. Hormone levels in the male parent affect the sex ratio of sperm in humans.

The fox and cooper’s hawk would be ___________________ consumers and considered ______________ predators in this food web.
Answer:
The correct answers are "tertiary; top".
Explanation:
Tertiary consumers are animals that eat other animals that are carnivorous as well. This is the case of the fox and the cooper's hawk. Foxes are omnivore animals that eat other animals like mice, which eat insects that eat plants sequentially. Cooper's hawks are also tertiary consumers, since they eat animals that are secondary consumers like frogs. This characteristic of both the fox and copper's hawk make them top predators in food webs.
Final answer:
The fox and cooper's hawk are higher-level consumers and efficient predators within a food web, maintaining ecological balance by controlling prey populations. They and their prey have adaptations for survival through natural selection. If removed from the food web, it could lead to shifts in the roles of other species.
Explanation:
The fox and cooper's hawk would be higher-level consumers and considered efficient predators in a food web. As higher-level consumers, they prey on various organisms below them in the food chain, including primary consumers like caterpillars and other smaller animals. Their role as predators is crucial for maintaining the balance in an ecosystem as they help control the population of these primary consumers.
Predation involves adaptations that both predators and prey develop through natural selection, such as camouflage. This is seen in both terrestrial and aquatic ecosystems, as demonstrated by the varied predatory relationships within food webs. The adaptations ensure the survival of these species within their respective habitats, allowing them to effectively hunt or evade predators.
In the case of food webs, secondary and tertiary consumers play a role in keeping the system balanced. If one species were to be removed, others in the web could potentially shift roles, although this is an oversimplification as entire ecosystems can be affected by the loss of a single predator or prey species.
