Answer:
word to my dead When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. These individuals will be more likely to survive and pass on their traits to their offspring. Over many generations, these favorable adaptations build up in a population. This may lead to speciation, which is the development of a new species.

What characteristics of the blood cell helps it to pass freely through blood capillaries
Answer:
The cell is flexible and assumes a bell shape as it passes through extremely small blood vessels. It is covered with a membrane composed of lipids and proteins, lacks a nucleus, and contains hemoglobin—a red iron-rich protein that binds oxygen.
Answer:
The cell is flexible and takes the form of a bell through extremely small blood vessels. It is clothed in a fluid and protein-membrane, lacks a nucleus, and has hemoglobin—a rich red iron protein that binds oxygen.
Explanation:
The hemoglobin in red blood cells contains four iron-binding heme groups.
Heme groups of hemoglobin are binding on oxygen. Each molecule of hemoglobin can bind up to four molecules of oxygen.
Hemoglobin has a cooperative binding affinity to oxygen. The saturation of the molecule increases by oxygen. The connection of the initial molecule of oxygen affects the form of the other binding sites. For additional oxygen molecules, the binding becomes more favorable.
The four iron-binding hemo-groups are located in each hemoglobin molecule. Hemoglobin is known as oxygen-bound hemoglobin.
The reversible carbon dioxide is transformed into the carbonic acid reaction by the enzyme carbenoid anhydrase by the Red blood cells altering the blood PH.
Instead of being converted to carbonic acid, pH is controlled by carbon dioxide bindings to hemoglobin.
CO2: The enzyme found in RBCs catalyzing the reaction between carbonic anhydrase and carbonate dioxide and water.
Co-operative binding: When a first molecule is binding to a binding location, the same molecule is favored for the remainder of the binding locations by means of increased binding affinity.

Which of the following pieces of evidence would best support the argument that humans are more evolutionarily related to fish than they are to insects? (1 point) The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans, O All these organisms require oxygen to survive. O The earliest fish fossils are found in the lowest strata of sedimentary rocks, followed by insects, and then humans. O Fossils of ancient fish and human ancestors have been discovered in the same sedimentary rock layers.
Answer:
The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans,
Explanation:
It tells you that fish and humans have very similar embryo development (fetus development) while humans and insects develop very differently. Therefore, that supports the argument that humans are more like fish than insects.
Answer:
(Q1) Most people develop wisdom teeth by early adulthood. Wisdom teeth can cause pain or crowd out their other teeth, so many people have these teeth removed. Wisdom teeth in modern humans do not perform a crucial life function.
(Answer)They are vestigial structures that once performed an important function for human ancestors.
(Q2) Which statement is true?
(Answer) Imprints of leaves or footprints in sedimentary rock are fossils.
(Q3) Which statement about these fossils is supported by the evidence in the diagram?
(Answer) Homo erectus is the most recent ancestor to modern humans.
(Q4) Which of the following pieces of evidence would best support the argument that humans are more evolutionarily related to fish than they are to insects?
(Answer) The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans.
(Q5) Human embryos have tails, which become tail bones before birth. Tails also appear in fish, reptiles, amphibians, birds, and mammals. Humans also have hair and produce milk to nourish the young, which is unique to mammals. What does this indicate?
(Answer) a close evolutionary connection between humans and many other mammals

what is the part of endoplasmic reticulum without proteins attached?
Answer:
Regions of ER that lack bound ribosomes are called smooth endoplasmic reticulum, or smooth ER.
Answer:
The ER regions lacking bonded ribosomes are referred to as the smooth or smooth endoplasmic reticulum.
Explanation:
The Endoplasmic reticulum is a membrane network within the cell that transmits proteins and other molecules. Proteins called ribosomes are assembled at organelles. The ribosomes that are assembled to the endoplasmic reticulum give it a rough look when proteins are intended for cell membrane or export from the cells. Smooth endoplasmic ribosomes are absent and help to synthesize and concentrate various cell-required substances.
Either a smooth or rough endoplasmic reticulum is capable of producing protein in general for the rest of the cell to function. The raw endoplasmic reticulum contains ribosomes, small, red organelles that make these proteins. Sometimes the proteins remain inside the endoplasmic reticulum when made incorrectly.
It is retained and the endoplasmic reticulum is engulfed because it appears to be stuck in a way that does not lead the protein where it is supposed to go. There is also the smooth endoplasmic reticulum on which these ribosomes are not contained. This smooth endoplasmic reticulum produces other materials that the cell needs. The endoplasmic reticulum is an organelle that actually produces proteins and substances that are necessary for the rest of the cell.

Describe how organ systems interact to get oxygen to the cells
The body's cells are supplied with oxygen and nutrients through the heart, blood, and blood vessels. Blood transports carbon dioxide to the lungs (for exhale) and picks up oxygen through the network of arteries, veins, and capillaries.
What is oxygen in the body?Our bodies require a specific amount of oxygen to function effectively since oxygen is necessary for life. When you breathe (inhale), oxygen enters your body through your mouth or nose and travels through your lungs into your bloodstream.
Oxygen inhaled by the lungs is also carried by your blood. Your body's other cells receive oxygen and nutrition from your circulatory system, which then collects any waste products they produce, including carbon dioxide, and transports them to your kidneys and lungs for elimination.
Therefore, the blood collects food nutrients from the small intestine and transports them to every cell in the body.
