Elephant tusks are either present or absent due to genetics, specifically the existence of key genes that regulate tusk growth. Environmental elements, however, can also affect the proportion of tuskless elephants in a population.
Elephants are frequently hunted down during conflicts or wars for their ivory tusks, which are highly sought-after on the illicit market. Over time, the population of elephants with tusks may decline as a result of this selective hunting of those with them.
The age range of 10 to 20 years old is essential because it coincides with the period of time when elephants usually begin to grow their tusks. Around the age of 6 to 8 years, young elephants may start developing their tusks, and by the time they are 10 to 20 years old, their tusks should typically be more noticeable and developed.
It is possible that many young elephants with developing tusks will be killed if a conflict or a period of rampant poaching takes place during this crucial time, which will reduce the number of tusked elephants in the population. After such a conflict or a period of heavy poaching, there can be a larger percentage of tuskless elephants between the ages of 10 and 20.
This theory makes the assumption that there was greater poaching or selective hunting occurring during the conflict, which would have a disproportionately negative effect on elephants with tusks. In order to provide a more comprehensive knowledge of the issue, additional examination of local conditions and data would be required. The individual situations and variables affecting elephant populations can differ.

why is deforestation a threat to Yellowstone National Park?
Answer:
Deforestation causes loss of animal and plant species due to their lack of habitat. A huge portion of animals and plant species live in forests so if we take that away from them how are they supposed to survive? Not only does deforestation threaten species known to us, but also threatens species we haven't even discovered yet.
Explanation:
This isn't necessarily for Yellowstone but for all national parks ^

Heavy snow and strong winds
Clear skies with no precipitation
Answer:
light rain sleet and snow
A)
Column shaped clouds usually mean that heavy precipitation is on the way.
A fair amount of the world's precipitation falls as snow or some other solid water form. Actually, outside the tropical regions, it is likely that the much of the precipitation begins in the solid form and only becomes liquid rain when it melts while falling through air with temperatures above freezing.

What differentiates passive transport from active transport?
Group of answer choices
Molecules move down a concentration gradient during passive transport.
Passive transport involves molecules moving across the cell membrane.
ATP is needed for passive transport to occur.
Proteins have a role in passive transport.
Answer:
The movement of molecules across a membrane without the input of energy is known as passive transport. When energy (ATP) is needed, the movement is known as active transport. Active transport moves molecules against their concentration gradient, from an area of low concentration to an area of high concentration

blastocyst
zygote
Answer:
fetus
Explanation:
i just did the test
During the development of human offspring, the fetus begins to hear and see that is in the first option as the fetus is the stage of human development that occurs after the embryonic stage.
What is a fetus?During this fetal stage, the structures that began to form during the embryonic stage continue to grow and develop, and the fetus begins to hear and see during this stage, as the ears and eyes are formed and become functional, and it also develops many other organs and systems during this stage, including the respiratory, digestive, etc. As a result, the fetus is the stage at which more complex structures develop, and it later develops into the fully mature baby.
As a result, the fetus begins to hear and see during the development of human offspring, which is in the first option because the fetus is the stage of human development that occurs after the embryonic stage.

Do you have more cells now than you did when you were five?
Answer:
No After your cell dies of another one come. Your cells are still the same
Explanation:
When you age, cells do divide and reproduce more cells. However when you age the reproduction process of cells gets slower and they can die off before they can reproduce. There can be many problems with your cells that can make cell count lower such as Atrophy, and Dysplasia. When you age, cells are a contributing factor of making you age. They can change your skin, face, etc.. So the answer would be no, you would not have more than you did when you were five.
During cell reproduction, chromatin fibers coil up into structures called
a. chromosomes
b. lysosomes
c. nucleoli
d. ribosomes
During cell reproduction, chromatin fibers coil up into structures called chromosomes. Therefore, the correct option is A.
What are chromosomes?Chromosomes are structures made up of DNA and proteins that are found in the nucleus of the cell. They contain genetic information That are responsible for the inherited characteristics of the organisms such as eye color, hair color, height etc.
Chromosomes play a crucial role in cell division, as they ensure the proper distribution of genetic material to the daughter cells.
During cell division, chromosomes are replicated and then separated into daughter cells, ensuring that each cell receives a complete set of chromosome.
The number and arrangement of a chromosome vary depending on the species, but all human cells except the sperm and egg cell contains 23 pairs of chromosomes. Hence, the correct option is A.

The arrows in a food chain represent the flow of energy or the transfer of nutrients between different organisms in an ecosystem.
They indicate the direction of energy transfer, showing which organism is being consumed by another. The arrow always points from the organism being consumed (prey) to the organism consuming it (predator).
The primary producers, such as plants or algae, are at the beginning of the food chain and transfer energy to herbivores (primary consumers), which are then consumed by carnivores (secondary consumers) or other higher-level consumers.
The arrows help depict the interconnectedness and energy flow within an ecosystem, illustrating the feeding relationships between organisms.
