blood flows more slowly in the capillaries than in the aorta. why?
Answer:
because it a smaller part
Explanation:
Due to the capillaries' large overall cross-sectional area, blood flow there is slow, allowing for adequate nutrition exchange.
How blood flows through blood vessels?The rate of blood flow dramatically decreases as it enters arteries, arterioles, and eventually, capillary beds, slowing to roughly 0.026 cm/sec, or 1,000 times slower than the aorta.
The capillaries, where blood flow is the slowest, provide time for the exchange of gases and nutrients. A force that opposes a fluid's flow is called resistance.
The majority of blood vessel resistance is caused by the size of the vessel. Blood flow reduces as vessel diameter shrinks due to an increase in resistance.
Therefore, the high total cross-sectional area capillaries blood flows more slowly.

The cell in the diagram is a plant cell because it has chloroplasts and a cell wall.
There are two types of cells animal cells, which are the ones that humans and animals have, and plant cells, which are the ones that plants and trees have. They share some organelles, but they also have some that are specific to each type.
The plant cell parts in the picture are:
Rough Endoplasmic Reticulum: it is where the ribosomes are. The synthesis of proteins happens there.Chloroplast: it is an organelle-specific of plant cells. They are in charge of photosynthesis.Cell wall: it is only present in plant cells. It surrounds the membrane.Mitochondria: It is the place that generates the energy that the cell needs.Vacuole: they are bigger in cell plants than in animal plants. It has many functions, but one is to store water.Membrane: it draws the limits of the cell.Golgi Apparatus: it is the place where proteins go to be distributed.Nucleus: it contains DNA, and it has a membrane around it.The nucleolus: is the larger part of the nucleus. It is in contact with the endoplasmic reticulum.To sum up, the plant cell has a bigger vacuole than the animal cell; it also has chloroplasts and a cell wall, which are not present in the animal cell.

anthropologists are suspicious of naturalizing discourses because
Anthropologists are suspicious of naturalizing discourses because they ignore historical evidence showing how present-day arrangements contrast.
What are the roles of anthropologist?An anthropologist is a person engaged in the practice of anthropology. Anthropology is the study of aspects of humans within past and present societies.
Creating research plans that address underrepresented topics. Executing research protocols that adopt a holistic study design. Promoting the co-creation of information by employing participatory approaches.
Anthropologists, people who conduct anthropological studies, identify aspects of being human as their focus. For example, one anthropologist might explore mating rituals of a small tribe in New Guinea.

Explain how a father with brown eyes and a mother with blue eyes can have children
with either brown or blue eyes. Remember to use complete sentences and correct
grammar.
Answer:
Brown eyes are a dominant trait.
Explanation:
Brown eyes are a dominant trait, and blue eyes are a recessive trait. If the father has brown eyes, they can have either a BB or Bb genotype; the mother must have a bb genotype in order for her eyes to be blue.
Refer to the Punnett Square below to see how it's possible for this mother and father to produce children with both colored eyes.
explain how the internal parts of a leaf are adapted for photosynthesis
Explanation:
Leaves have a large surface area so more light hits them. The upper epidermis of the leaf is transparent, allowing light to enter the leaf. The palisade cells contain many chloroplasts which allow light to be converted into energy by the leaf.
Choose the answer that correctly lists, in chronological order, the events involved in synaptic transmission.
a: A nerve impulse reaches the synaptic knob.
b: Neurotransmitter molecules diffuse across the synaptic cleft.
c: A nerve impulse begins in the postsynaptic cell.
d: Neurotransmitter molecules bind to receptors in the postsynaptic cell.
e: A voltage change occurs in the postsynaptic cell.
Answer: hi im brain bot
im not sure i know this one im stumped
Explanation:
The event occurs as nerve impulse reaches the synaptic knob, neurotransmitter molecules diffuse across the synaptic cleft. These molecules bind to receptors in the postsynaptic cell and voltage change occurs in the postsynaptic cell. A nerve impulse begins in the postsynaptic cell. The correct option is C.
What is synaptic transmission?The metabolic pathway by which a neuron interacts with a target cell across a synapse is known as synaptic transmission.
Chemical synaptic transmission is characterized by the release of a neurotransmitter from the presynaptic neuron and the binding of the neurotransmitter to specific post-synaptic receptors.
Synaptic transmission is the process by which a nerve impulse (action potential) travels from the presynaptic neuron to the post-synaptic neuron across the synaptic gap. An action potential is an electrical impulse that travels down the axon of a neuron.
As the nerve impulse arrives at the synaptic knob, neurotransmitter molecules diffuse across the synaptic cleft. These molecules bind to receptors in the postsynaptic cell, causing voltage changes in the cell. and finally nerve impulse begins in the postsynaptic cell.
Thus, the correct option is C.

How many carbon atoms does glucose have
Answer:
six carbon atoms
Explanation:
Glucose has an aldehyde group (-CHO) on carbon atom number one and is therefore called an “aldose,” also it has six carbon atoms (a hexose) so it can be called an “aldohexose.” The reactive group on fructose, however, is a ketone group (-C=0) on carbon number two.

How can I use the analogy of building blocks to explain how genes relate to the diversity of life?
Answer:
-Building blocks are the fundamentals to an overall result, in this case being the characteristics of a human being.
-This is related to genes as the variety of building blocks can make a completely different "outcome" just as a different gene can trigger a different characteristic.
- Without different building blocks, all outcomes will be the same, just as humans. So a variety of "building blocks" are needed for diversity.

The diagram shows the approximate amounts of carbon, in gigatons (Gt) per year, that move through the primary processes
of the carbon cycle. The numbers in yellow are due to natural processes, and the numbers in red are the result of human
actions. Based on this diagram, complete the statements.
Human activities release 9 gigatons of carbon into the atmosphere each year.
Human activities remove 5 gigatons of carbon from the atmosphere each year.
Humans’ net contribution of atmospheric carbon to the atmosphere is 4 gigatons each year.
9 gigatonnes of carbon are released into the atmosphere annually by human activity. Each year, 5 gigatonnes of carbon are removed from the atmosphere by human activity.
Thus, Each year, 4 gigatons of atmospheric carbon are added to the atmosphere as a result of human activity.
A fundamental mechanism that controls the movement of carbon dioxide and other carbon compounds between the atmosphere, oceans, soil, and living things on Earth is known as the carbon cycle. The concentration of carbon in various reservoirs is influenced by a variety of natural and human factors.
Plants and other photosynthetic creatures take up about 120 Gt of carbon each year from the atmosphere through the process of photosynthesis (yellow).
Thus, 9 gigatonnes of carbon are released into the atmosphere annually by human activity. Each year, 5 gigatonnes of carbon are removed from the atmosphere by human activity.
