Did dinosaurs and humans exist at the same time? What is your evidence?
Answers
Answer:
No! Humans took 65 million years to arrive on the globe after the dinosaurs died out. During the dinosaur period, small mammals such as shrew-sized primates existed.
Explanation:
Hope this helps you!!!!! :D
Of course the ancestors of humans were contemporary with the dinosaurs. Yes, they were alive some 65 million years ago, BUT you wouldn't recognize them as human. Our ancestors back then were little furry creatures with tails, about the size of a rat. Close inspection might have revealed that even back then they had some human like features. They probably had forward directed eyes to give them binocular vision. They could possIbly see in colour. They would have had 5 digits on each limb as we do. They probably had approximately the same number of teeth as we do. They most definitely had warm blood, nipples and fed their young on milk. They possibly had nails rather than claws.
Now, great big creatures with enormous bones like dinosaurs, whales and mammoths, fossilize well, but creatures with small fragile skeletons like hummingbirds, bats, mice, shrews and the ancient shrew like ancestors of humans would be fantastically lucky to be fossilized at all. Their little carcasses would be eaten by predators or scavengers, by ants, maggots and beetles. Only a fool would hope ever to find a fossil of one of our direct ancestors from the time of the dinosaurs, but that doesn't mean they didn't exist. We know they existed because we exist today. Remember, all forms of life present today, have always existed at every time in the past, but not necessarily in a shape we would instantly recognize as ancestral to their present form

All - growth, exchange of gases, excretion, reproduction, and death (option d).
All living organisms undergo various life processes to maintain their existence. Let's analyze each option to determine which life processes are carried out by an organism's cells:
A. Only growth and exchange of gases: While cells are involved in growth and exchange of gases, they also participate in other life processes. This option is incomplete.
B. Only growth, exchange of gases, and reproduction: Cells play a crucial role in reproduction as they are responsible for the production of gametes and the process of cell division. However, there are additional life processes that cells also undertake.
C. Only growth, exchange of gases, excretion, and reproduction: This option includes excretion in addition to growth, exchange of gases, and reproduction. Cells participate in excretion by eliminating waste materials. However, there is one more life process that cells experience.
D. All - growth, exchange of gases, excretion, reproduction, and death: This option encompasses all the mentioned life processes. Cells are involved in growth as they undergo cell division and increase in number. They exchange gases through processes like respiration. Cells excrete waste products. They participate in reproduction through the formation of gametes and cell division. Lastly, cells also experience death as they have a limited lifespan.
Therefore, the correct answer is D. All - growth, exchange of gases, excretion, reproduction, and death.

Nerve Tissue: In order to ensure the heart muscle tissues contracts at the right frequency, your heart also contains nerve tissue which consists of nerve cells. Nerve cells are long and thin and can transmit impulses over long distances very quickly. We'll come back to nerve cells later in this unit.
Blood Tissue: A functioning heart obviously contains a large amount of blood tissue - both in the chambers to be pumped, but also in the blood vessels supplying the heart muscle tissue with the oxygen and glucose it needs in order to respire to produce the ATP energy it needs to contract. Blood tissue contains red blood cells which are specialised to absorb, carry and release oxygen. We'll revisit blood later in this unit.
STRUCTURES AND FUNCTIONS The graph below shows the mating seasons of several species of frogs. Based on the information shown in the graph, do the peeper frog and the leopard frog likely have barriers to reproduction in addition to slightly different mating seasons? What other barriers might be in operation? Explain your answers.
Answers
One possible barrier to reproduction could be geographic isolation. If the habitats of the two frog species do not overlap or are separated by a physical barrier, such as a river or mountain range, then the frogs may not have the opportunity to mate and produce offspring.
Another possible barrier could be behavioral isolation. If the mating calls of the two frog species differ significantly, then the frogs may not recognize each other as potential mates and therefore not mate.
Lastly, genetic incompatibility may also act as a barrier to reproduction. Even if the two species were to mate and produce offspring, the resulting hybrid offspring may not be viable or fertile, which would prevent any gene flow between the two species.
Overall, the slightly different mating seasons between the peeper frog and the leopard frog may be an important factor in preventing interbreeding, but other barriers such as geographic isolation, behavioral isolation, and genetic incompatibility may also be in operation.
the cell constantly exchanges materials by bringing nutrients in from the external environment and shuttling unwanted by-products back out. which term describes the process of by which internal materials are transported out of the cell?
Answers
The term that describes the process by which internal materials are transported out of the cell is "exocytosis".
Exocytosis is a biological process by which cells release substances outside of the cell through the fusion of vesicles with the plasma membrane. This process plays a crucial role in various cellular functions, including cell-to-cell communication, secretion of hormones and enzymes, and the removal of waste products.
During exocytosis, the vesicles containing the substances to be released move toward the plasma membrane, where they dock and fuse with the membrane. The contents of the vesicles are then released outside of the cell, either by diffusion or through the opening of membrane channels. Exocytosis is essential for many physiological processes, including neurotransmitter release in the nervous system, insulin release by pancreatic cells, and the release of digestive enzymes by the pancreas and salivary glands.

The frontal lobe is located infront of the brain and extends from the area located at the back of the forehead. It is responsible for higher cognitive functions like memory, emotions, impulse control, problem solving, social interaction, and motor function. The three frequently used techniques to measure the frontal lobe are Magnetic Resonance Imaging (MRI), magnetoencephalography (MEG) and electroencephalography (EEG).
Damage to the frontal lobe can cause several symptoms such as behavioral problems, depression, and loss of strenght in the muscles. Also conditions like stroke, head trauma, and dementia can be seen in individual with damage frontal lobe.

What is the net charge of an ion that has 9 protons 11 neutrons and 11 electrons
Answers
2-
Explanation:Net charge describes the overall negative or positive charge of an atom or compound. Also, note that it is common in chemistry to write the sign of the charge after the number. Nevertheless, the charges +1 and 1+ are completely the same.
Calculating Charge
To find the charge of an atom you should look at the number of protons and electrons. Since neutrons have a neutral charge, aka no charge, they do not factor into net charge. On the other hand, protons have a positive charge and electrons have a negative charge. Each proton has a 1+ charge and each electron has a 1- charge.
To find the net charge find the total charge of the electrons and the total charge of protons, then add them together. Since there are 9 protons, the total proton charge is 9+. There are 11 electrons, so the total electron charge is 11-. For the purposes of doing the math, we can move the sign to the front.
(+9) + (-11) = -2Thus, the net charge is 2-.
Anions and Cations
To work with ions it is important to understand the vocabulary surrounding ions. Firstly, negative ions, like the one described in the question, are called anions. You can remember this as "A Negative ION". Also, positive ions, ions with positive net charges, are called cations. You can remember that the "t" looks like a plus sign.

Clays contain minerals iron pyrite that may act as catalysts to speed up reactions.E. Clays are a source of ATP to run chemical reactions.
Answers
The fact that clays often have charged surfaces is important in the formation of polymers of organic macromolecules because clays contain minerals iron pyrite that may act as catalysts to speed up reactions. Therefore, the correct answer is D.
The charged surfaces of clays may have been important in the formation of polymers of organic macromolecules because they can act as catalysts to speed up reactions. Clay minerals, such as iron pyrite, have the ability to attract and hold onto organic molecules, bringing them closer together and increasing the likelihood of them reacting to form larger molecules. This catalytic property of clays may have played a crucial role in the formation of early life on Earth, by facilitating the formation of complex organic molecules like DNA and RNA.
