Their new study shows that humans are strange predators. Unlike other animals, we target adult prey in large numbers. That is a practice that can push populations of those prey into decline, the researchers warn. People mainly target — at least among wild mammals and fishes — prey that are old enough to reproduce.
Humans are considered to be apex predators in their ecosystems due to their ability to manipulate and dominate other species through hunting, agriculture and urbanization.
Why are human predators?Humans are considered to be apex predators in their ecosystem due to their ability to manipulate and change their environment to suit their needs. Humans have the ability to hunt and consume a wide variety of other organisms, including other predators. Humans also have a significant impact on the environment through activities such as deforestation, pollution, and hunting.
However, humans are also capable of acting as stewards of the environment and preserving biodiversity through conservation efforts. The relationship between humans and their ecosystem is complex and multifaceted.

The organisms that are usually fossilized
by replacement are what?
Answer:
when the original shell or bone dissolves away and is replaced by a different mineral; when this occurs with permineralization, it is called petrification. In compression, the most common form of fossilization of leaves and ferns, a dark imprint of the fossil remains.

How did the development of a waxy cuticle help plants adapt to life on land?
O A. The cuticle minimized water loss from leaves.
B. The cuticle absorbed nutrients from the soil.
C. The cuticle increased photosynthesis.
O D. The cuticle protected reproductive structures.
SUBMIT
Answer:
a
Explanation:
The cuticle in the plants minimizes the water loss or transpiration from leaves. The correct option is A.
What is transpiration?Transpiration is the process by which water vapor is lost via the stomata of plants. When the weather is very hot, the plant's loss of water vapor cools it down, and moisture from the stem and roots moves upwards or is 'pulled' into the leaves.
The evaporation of extra water from stomata in plant leaves is known as transpiration. It is necessary for some upward movement of water in plants. It aids in the regulation of plant temperature.
To transpire, water vapor must diffuse through this motionless layer from the stomata to the atmosphere, where it will be removed by moving air. The cuticle present in the waxy leaves prevent excess transpiration.
Thus, the correct option is A.

B. It attacks neurons in the nervous system and causes paralysis
C. It attacks and destroys certain cells in the bodies of its host organisms.
D. It has viral DNA that is transmitted through direct contact with infected persons
Answer: A
It has viral DNA that remains dormant until environmental conditions are right.
HIV is a unique human RNA virus, capable of infecting cells of the immune system.
Plz mark brainliest:)
It attacks and destroys certain cells in the bodies of its host organisms. Therefore, option (C) is correct.
What is HIV?HIV, or human immunodeficiency virus, attacks and destroys a specific type of immune cell called CD4+ T cells. These cells play a critical role in the immune system, and their destruction leads to a loss of immunity and the development of acquired immunodeficiency syndrome (AIDS). HIV is unique in that it specifically targets and attacks these cells, leading to a gradual decline in the body's ability to fight off infections and diseases.
HIV is primarily spread through sexual contact, but can also be spread through sharing needles or from mother to child during pregnancy, childbirth, or breastfeeding. HIV can lead to AIDS (Acquired Immunodeficiency Syndrome) if left untreated.

Answer:
120 cm
Explanation:
volume is length x width x height so 3 x 4 is 12 and 12 x 10 is 120cm
Answer:
120 cm^3
Explanation:
V= width x length x height
3 x 4 x 10 = 120
and when you multiply centimeters,
cm x cm = cm^2
cm x cm x cm = cm^3

Which statement best describes the effect on water transport across the cell membrane if the aquaporin in the figure ceases to function?
Answer:
Water molecules will still be able to move across the cell membrane but at a slower rate.
Explanation:
D isn’t a sensible answer because Aquaporin is a protein with a role to regulate water transport. In its absence, of course there will be defects. And A is impossible due to the existence of active transport. (I also looked it up) (:
Answer:
Water molecules will still be able to move across the cell membrane but at a slower rate.
Explanation:
The aquaporin facilitates water passage, but water can still move across the membrane by osmosis. (osmosis requires no channel protein, but aquaporin makes diffusion faster).

A) height of the tomato plants
B) pH of the soil
C) specific variety of tomato plants used
D) pH of enzymes is tomato leaf cells
Answer:
A. Height of tomato plants
Explanation:
The dependent variable in an experiment is the variable that the experimenter measures or the variable that responds to changes made to the independent variable. The dependent variable is dependent on the independent variable.
In this experiment conducted to determine how different PH values of soil will affect the growth of tomato plants, the growth of the plants is measured by their height. Hence, the dependent variable is the HEIGHT OF THE PLANTS.
