Are Mammut mastodons the same species as Paleomastodons?
Answer:
These woolly mammoths were not closely related to mastodons. Mammoths and mastodons may have once roamed the Earth together, but they represent two distinct species of the Proboscidean family. ... Mammoths and modern elephants are closely related members of the same family (Elephantidae).
Explanation:
No, they are not the same species.
Are mammoths and mastodons the same species?Despite the superficial resemblance, mastodons were distinct from mammoths. Mastodons were shorter and stockier than mammoths with shorter, straighter tusks. Mastodons were wood browsers and their molars have pointed cones specially adapted for eating woody browse.
Are mastodons and mammoths related?While mastodons look a lot like modern elephants, they are not closely related. The ancestors of modern elephants and mammoths went their separate ways about 5 million years ago, and mastodons branched off even earlier, about 25 million years ago.

How do environmental signals, like light influence the distribution of auxin in a plant? A. By increasing the concentration of auxin B. By destroying the auxin C. By causing auxin to migrate in to the shaded portion D. By decreasing the cells sensitivity the auxin
Answer:
C. By causing auxin to migrate in to the shaded portion
Explanation:
Auxin is the most important plant hormone involved in the apical growth of plant parts. Auxin is evenly distributed in a plant with a normal light condition, however, when a particular part of a plant is exposed to sunlight, that illuminated part contains less auxin. The hormone is transported to the shady part of the plant via diffusion.
This causes more auxin to be present in the shady part than the illuminated part, hence, the shady part experiences a faster and elongated growth. This elongated growth in the shaded portion of the plant causes it to grow towards the direction of the light, a process called PHOTOTROPISM.

A new development involves a network of plastic tubes being printed within an organ. After the whole organ is printed, these plastic tubes are dissolved, leaving a network of empty tunnels.
Why does the organ need to have the empty tunnels within it?
Answer:
These are needed to mimic the blood vessels which these organs will use for the supply or drainage of fluids e.g blood.
In addition the empty tunnels serve as the routes for nutrients and oxygen supply for the organ.
In summary the tunnels provided a vascular structure to support the organ

A tick and a dog have this type of relationship?
*mutualism
*commensalism
*neutralism
*parasitism
Answer:
Parasitism
Explanation:
First, let's define each term.
Mutualism: A symbiotic relationship where both organisms benefit
Commensalism: An association where one organism benefits, and the other is not harmed or benefited.
Neutralism: 2 organism interact but they have no effect on each other.
Parasitism: A symbiotic relationship where a parasite lives in or on another organism and harms the organism.
A dog and a tick are an example of parasitism. The tick lives on the dog and drinks the dog's blood. This is the food for the tick, so the tick is benefiting by gaining a food source. The dog can be harmed if the tick is carrying a disease, such as Lyme disease.

What is heart attack? What are its causes?
Answer:
MEANING
A heart attack is a medical emergency. A heart attack usually occurs when a blood clot blocks blood flow to the heart. Without blood, tissue loses oxygen and dies.
A heart attack occurs when one or more of your coronary arteries become blocked. Over time, a coronary artery can narrow from the buildup of various substances, including cholesterol (atherosclerosis). This condition, known as coronary artery disease, causes most heart attacks.
CAUSES:
Chest Pain, Pressure, Fullness, or Discomfort.
Discomfort in other areas of your body.
Difficulty breathing and dizziness.
Nausea and cold sweats.

Compounds like the pesticide DDT may bring about the evolution of new strains of organisms by...?
(1) destroying food producers
(2) acting as natural selecting agent
(3) mixing two different sets of genes
(4) creating new ecological niches
Answer:
(2) acting as natural selecting agent
Explanation:
Compounds like the pesticide DDT may bring about the evolution of new strains of organisms by acting as a natural selecting agent.
Evolution is generally defined as a gradual change to the characteristics of organisms over a period of time.
When DDT is used on a particular population of pest, those that are weak within the population die off, leaving only those that are strong within the population to survive and multiply. The DDT acts a selecting agent for the survival gene in the pest and the survived gene eventually evolve into a new, DDT-resistant strain pest in no time.
The correct option is option (2).

Can seaweed help curb global warming? (At least 7 sentences)
Answer:
Professor and climate change activist Tim Flannery believes that massive farms of seaweed, a crop with enormous carbon sequestration capabilities, could potentially draw enough carbon dioxide from the atmosphere in a short enough time frame to mitigate some of the worst effects of climate change. Flannery acknowledges that his radical approach could raise some negative externalities, and sweeping carbon under the ocean isn’t a permanent solution. But for those who worry that the climate crisis is a lost cause, he offers reassurance that climate change is a soluble issue.

What is cell division?There are two types of cell division. These are mitosis and meiosis. Most of the time when people talk about cell division, they are referring to mitosis. This is the process of the formation of new body cells. Meiosis is another kind of cell division that results in the formation of egg and sperm cells.
Mitosis is the fundamental process of life. During the process of mitosis, a cell duplicates itself along with all of its contents. This includes the chromosomes of the cells. Then the cell splits to form two identical daughter cells.
All the steps of mitosis are carefully controlled by certain genes because of the critical nature of this process. When mitosis is not being regulated correctly, various health problems such as cancer can arise.
Meiosis is the next type of cell division. This ensures that humans have the same number of chromosomes in each generation. Meiosis is a two-step process that reduces the chromosome number by half, from 46 to 23, to form sperm and egg cells. This is also called the reduction division.
Therefore the correct option is A.

Explanation:
Mendel chose pea plants for his experiments because they have easily identifiable traits like pea plants are either tall or short, which is an easy trait to observe. Also, pea plants grow quickly, so he could complete many experiments in a short period of time.
Some adaptations, on the other hand, become useless. These adaptations are vestigial: remaining but functionless. Whales and dolphins have vestigial leg bones, the remains of an adaptation (legs) that their ancestors used to walk. Why did the author include this selection?
Answer:
This is because vestigial parts are usually homologous to most of the structures that are functional in other species of organisms. E.g.. the Vestigial legs which are non functional in whale and Dolphins, are useful to other organisms. Hence, if these organisms possessed these structures, they should share certain characteristics with each other.Therefore these organisms can be said to evolved from one another.Thus their vestigial organism should be included by the author as evidence of evolution.

Why do cells use fat and starch for long-term energy storage instead of ATP molecules?
A.) ATP is used for long-term storage, while fat and starch are used for immediate energy.
B.) ATP is used for short-term energy and to build molecules of starch and fat.
C.) Fat and starch are unstable and can be stored short-term, while ATP molecules are stable and stored long-term.
D.) Fat and starch are stable if used as energy immediately, while ATP is used as long-term storage
Answer:Cells use fat and starch for long term energy storage instead of ATP molecules because it is hard to breakdown fat in a very short time while ATP can be broken down in a very short time. ATP is mainly used while doing short bursts of exercises. Fats have a very strong bond of molecular chains and this makes it hard to breakdown quickly.
Explanation:
