When you stand and let your hands hang next to your sides for a few minutes, the bumps you see on your veins are the valves that help move blood to the larger veins.
What we know about vein valves.There are valves located throughout the veins in our bodies. Most of these are located in points where smaller venules fuse with the larger veins.
Their function is to prevent blood from flowing back into the smaller veins, thus helping with the normal blood flow of the body.
Given that the veins in our bodies are littered with small valves to help the blood return to the heart correctly, we can confirm that these are the small bumps that we can see when letting our hands down for a few mins, as they fill with the blood they try not to let flow back into the smaller veins.

Read the excerpt from "Bone Detective," by Lorraine Jean Hopping. While the dentist worked on the tiger’s teeth, Diane made an alginate impression of one of its huge paws. Then, the dentist used two cupped hands to pull the tongue out of the big cat’s mouth. The heavily muscled organ was almost as long as her foot. With the dentist still holding the tiger tongue in both hands, Diane quickly went to work. The pink surface was rough, like sandpaper, but floppy and wet. She coated the top with alginate and waited for it to set. Her 15 minutes were almost up. The tiger, so calm and soft, would soon wake up and be dangerous again. Slowly and carefully, Diane peeled off the soft impression to avoid tearing it. Based on this excerpt, what is the author’s attitude toward Diane France? The author feels Diane is rough and impatient in her work with the tiger. The author feels Diane is skillful and careful in her work with the tiger. The author feels Diane is anxious and distracted in her work with the tiger. The author feels Diane is light-hearted and humorous in her work with the tiger.

On any given day, the weather forecast might say that rain, snow, and sleet are expected. Which of the following statements is describing this area’s climate?
Group of answer choices
A. Last January it snowed for 17 days in a row.
B. Sleet is a combination of rain and snow.
C. The rain turned to sleet and snow later that afternoon.
D. Rain, snow and sleet are common during the month of December.
Answer:
C
Explanation:
Because it makes more sence
Frozen raindrops that hit the earth's surface are known as sleet (Ice Pellets). When sleet first forms, snow will be the precipitation that falls upwards. Thus, option C is correct.
What weather forecast rain, snow, and sleet are expected?Both sleet and freezing rain develop using the same fundamental mechanism: liquid droplets in a layer of warm air above the surface descend into a layer of freezing air close to the ground.
When snowflakes fall through a thin layer of warm air, they only partially melt, resulting in sleet.
These slushy drops then refreeze as they fall through a thick layer of icy air above the surface, and when they finally make it to the ground, they do so as frozen raindrops that bounce as they hit the ground.
When rain falls through a chilly layer and directly on the ground, it freezes on contact and forms a layer of ice. This is known as freezing rain.
Therefore, Snow that falls from a cloud and melts as it passes through an upper layer before falling back through a lower layer below freezing is known as sleet.

By which process does yeast produce the carbon dioxide responsible for bread rising?
A. Photosynthesis
B. glycolysis
C. cellular respiration
D. dehydration synthesis
Answer:
C. cellular respiration
Explanation:
Yeast produces the carbon dioxide responsible for bread rising by CELLULAR RESPIRATION
WHICH ORGANISM IS CALLED YEAST?
Yeast is an eukaryotic unicellular organism that belongs to the kingdom fungi. Cellular respiration is the metabolic process by which living organisms obtain energy in form of ATP by breaking down organic and inorganic substances.HOW DOES YEAST RESPIRE?
Yeast respires anaerobically via a kind of cellular respiration called FERMENTATION. In the process of fermentation, glucose is broken down to produce ethanol and carbon dioxide (CO2). In bread making, yeast is used to make dough rise. The carbon dioxide (CO2) produced during cellular respiration is what is responsible for the rising of bread.Learn more at: https://brainly.com/question/3126347

Answer:
B. Paternity
Explanation:
Edge 2020
The career that combines DNA technology and forensics is paternity testing. The correct option is B.
What is paternity testing?DNA testing examines an individual's DNA banding patterns to determine the identity or mutations of a specific gene.
Paternity testing is a type of DNA testing that is used to determine paternity and the true nature of a relationship.
The lab compares tissue samples from the mother, the child, and the man to determine what unique characteristics known as genetic markers the child shares with the mother and the man who may be the father.
The chromosomes that determine the gender of the baby (X and Y chromosomes). The mother's egg typically contributes an X chromosome, while the father's sperm contributes either an X or a Y chromosome.
These tests are extremely accurate in determining whether a man is the biological father of a child.
Thus, the correct option is B.

Explanation:
Sea turtles spend most of their lives at sea feeding on jellyfish. When it is time to lay their eggs, mature females come ashore. They dig nests in the sand along the coast, lay their eggs, and then return to the sea. The data below show the changing sea levels since the late 1800s.
If the current trend shown in the graph continues, what prediction is most likely regarding the future of sea turtles?
a. Fewer jellyfish will wash up on the beach for the turtles to feed on.
b. More predators will be found on the beaches to threaten the baby turtles.
c. The baby turtles will have to travel farther to reach the ocean.
d. The beaches on which turtles currently lay their eggs may go underwater.
Answer:
d. The beaches on which turtles currently lay their eggs may go underwater.
Explanation:
According to the graph, the beaches on which turtles currently lay their eggs may go underwater due to increase sea level with the passage of time. In the graph, we can see that sea level increases from 1880 to 2014 and the main reason for this increase is the climate change. Due to global warming the water present on the glacier starts melting and thus increase in sea level occurs so the beaches on which turtles currently lay their eggs may go underwater.
The process of forming ATP is? A) Digestion. B) Cellular Respiration. C) Metabolism. D) nutrition.
Answer:
[tex]\boxed {\boxed {\sf B. \ Cellular \ respiration}}[/tex]
Explanation:
First, let's analyze each process.
A. Digestion
This is the process of breaking down food.
B. Cellular respiration
This is the process of converting glucose and oxygen to carbon dioxide, water, and ATP.
C. Metabolism
This isn't really a process. It's the collection of all the chemical reactions in the body to keep the body functioning.
D. Nutrition
This term also isn't a process. Nutrition involves food, nutrients, and health.
We are looking for the process that forms ATP. Therefore, the best answer choice is B. Cellular respiration
The process of forming ATP is Cellular Respiration. Therefore option B is correct.
The process of forming ATP (Adenosine Triphosphate) is primarily through Cellular Respiration.
ATP is the main energy currency in cells, providing the energy needed for various cellular activities.
Cellular respiration is a series of metabolic reactions that occur in the mitochondria of cells, where organic molecules (such as glucose) are broken down and oxidized to release energy.
This energy is used to synthesize ATP from ADP (Adenosine Diphosphate) and inorganic phosphate (Pi).
Through cellular respiration, cells efficiently convert the energy stored in food molecules into a readily usable form of energy (ATP).
Which powers essential cellular processes, including muscle contraction, active transport, and synthesis of macromolecules.
Therefore option B Cellular Respiration is correct.

what are the three primary methods scientists use to group organisms into monophyletic clades? please provide examples for each. which has caused the major reorganization of phylogenies, i.e. the fall of the kingdoms, and why only recently?
Answer:Cladistics (/kləˈdɪstɪks/, from Greek κλάδος, kládos, "branch") is an approach to biological classification in which organisms are categorized in groups ("clades") based on the most recent common ancestor.
Explanation: Modern taxonomists seek to employ classification schemes that are consistent with the underlying evolutionary relationships among species. As shown below, phylogenetic analyses present a way to test existing Linnaean classifications (some of which predate widespread acceptance of the fact of evolution) and to determine which classifications are consistent with evolutionary history, and which require modification.
