How body responds when the body temperature increases
When body temperatures rise, the body reacts by increasing blood flow to the skin's surface, taking the heat from within the body to the surface. This means sweat. As the sweat evaporates, the body cools down.
Using 3-5 sentences explain how human activties can affect climate change.
Answer:
Human activities can affect climate change because of just how much waste we produce. One huge example is our burning problem, which slowly strips away at the ozone layer that protects animals from heat and melting snow. Because of the ozone layer, the arctic has been protected for many years but now it's slowly disappearing, melting ice and killing animals who have not learned to survive in such hot weather. Another example is when humans cut down too many trees to sustain the environment; it often causes a massive lack in natural oxygen and unroots many homes of small critters and worms. In conclusion, humans can heavily affect climate change because of our ignorance and how we refuse to learn for the future.

Temperature is vital for successful beer and wine making.why is it so important ?
Temperature is vital for successful beer and wine making is it so important because in this process bacteria are very helpful and important factor and for them temperature must be minimized.
What is the role of bacteria in the formation of beer?In the formation of beer bacteria plays a vital role as they totally perform a function and due to this there is a change in the taste and concentration of the beer.Temperature is vital for successful beer and wine making is it so important because in this process bacteria are very helpful and important factor and for them temperature must be minimized.
The process by which wine has been prepared is known as fermentation and ethanol has a colourless liquid which catches fire easily and it has been produced by the process of the natural fermentation of the sugars or alcohol. Ethanol has been also known as the alcohol which has colourless and slightly toxic chemical compound and the ethanol forms water as well as carbon dioxide.
Therefore, Temperature is vital for successful beer and wine making is it so important because in this process bacteria are very helpful and important factor and for them temperature must be minimized.

What type of food was discovered to make up the majority of the diet of human foragers (and, by extension, likely our ancient ancestors)
Plant foods such as nuts, fruits and roots was discovered to make up the majority of the diet of human foragers. Hominine ancestors depended on foraging.
Hominine ancestors (i.e., before the evolution of H. sapiens), depended on foraging for millions of years.
Foraging refers to the search for wild food resources, which are provided by nature by gathering different sources (e.g., plants, small animals, birds, insects, etc).
Nuts, fruits and roots represent excellent sources of food because they contain both macronutrients (lipids, proteins and carbohydrates) and micronutrients (i.e., minerals and vitamins).

Which phase of the cell cycle is longest? What phase of the cell cycle is the shortest?
Answer:
Interphase is the longest and metaphase is the shortest usually
Explanation:
Answer
The longest phase of the cell cycle is Interphase
The shortest phase of the cell cycle is the Mitotic phase
Explanation
In case of cells with a nucleus, the stages of the cycle are divided into two phases: Interphase and the Mitotic (M) phase.
During Interphase the cell grows and makes a copy of its DNA before moving into Mitosis.
During Mitotic phase the cell separates its DNA into two sets to create two genetically identical daughter cells.

How does your body respond to a decrease in blood glucose
Answer:
When blood sugar drops too low, the level of insulin declines and other cells in the pancreas release glucagon, which causes the liver to turn stored glycogen back into glucose and release it into the blood. This brings blood sugar levels back up to normal.
Explanation:
hope this helps!
MERRY CHRISTMAS AND HAPPY NEW 2022 YEAR! GOD BLESS YOU!!!
Answer:
Glucose is a sugar that comes from the foods we eat, and it's also formed and stored inside the body. It's the main source of energy for the cells of our body, and is carried to each cell through the bloodstream. Our brains depend on glucose to function, even when we're sleeping.
The blood glucose level is the amount of glucose in the blood. When these levels (also called blood sugar levels) drop too low, it's called hypoglycemia (pronounced: high-poe-gly-SEE-me-uh). Very low blood sugar levels can cause serious symptoms that need to be treated right away.
Low Blood Sugar Levels in Diabetes
People with diabetes can have low blood sugar levels because of the medicines they have to take to manage their diabetes. They may need a hormone called insulin or diabetes pills (or both) to help their bodies use the sugar in their blood.
These medicines help take the sugar out of the blood and get it into the body's cells, which makes the blood sugar level go down. But sometimes it's a tricky balancing act and blood sugar levels can get too low.
People with diabetes need to keep their blood sugars from getting too high or too low. Keeping blood sugar levels in a healthy range means balancing when and what they eat, and when they exercise with when they take medicines.

Please help!! What are Okazaki fragments?
Explanation:
Okazaki fragments are short sequences of DNA nucleotides (approximately 150 to 200 base pairs long in eukaryotes) which are synthesized discontinuously and later linked together by the enzyme DNA ligase to create the lagging strand during DNA replication.[1] They were discovered in the 1960s by the Japanese molecular biologists Reiji and Tsuneko Okazaki, along with the help of some of their colleagues
During DNA replication, the double helix is unwound and the complementary strands are separated by the enzyme DNA helicase, creating what is known as the DNA replication fork. Following this fork, DNA primase and DNA polymerase begin to act in order to create a new complementary strand. Because these enzymes can only work in the 5’ to 3’ direction, the two unwound template strands are replicated in different ways.[2] One strand, the leading strand, undergoes a continuous replication process since its template strand has 3’ to 5’ directionality, allowing the polymerase assembling the leading strand to follow the replication fork without interruption. The lagging strand, however, cannot be created in a continuous fashion because its template strand has 5’ to 3’ directionality, which means the polymerase must work backwards from the replication fork. This causes periodic breaks in the process of creating the lagging strand. The primase and polymerase move in the opposite direction of the fork, so the enzymes must repeatedly stop and start again while the DNA helicase breaks the strands apart. Once the fragments are made, DNA ligase connects them into a single, continuous strand.[3] The entire replication process is considered "semi-discontinuous" since one of the new strands is formed continuously and the other is not.[4]
[2]During the 1960s, Reiji and Tsuneko Okazaki conducted experiments involving DNA replication in the bacterium Escherichia coli. Before this time, it was commonly thought that replication was a continuous process for both strands, but the discoveries involving E. coli led to a new model of replication. The scientists found there was a discontinuous replication process by pulse-labeling DNA and observing changes that pointed to non-contiguous replication.

agonists generally _______ activity at the synapse while antagonists generally ______ activity at the synapse.
Agonists activate the receptor thereby increasing activity at the synapse while antagonists generally prevent agonists from activating the receptors thereby decreasing activity at the synapse.
An agonist is the component that has the ability to increase the activity carried out by another substance.The agonists work from their faculty of coupling to a cell-type receptor, in this way, they manage to generate a certain action in the cell.The antagonists are the compounds that cause the opposite when they bind to the receptor, they cause a blockade by decreasing the activation of a synaptic receptor.Therefore, we can conclude that agonists are compounds capable of increasing the action of synapse and blockers (antagonists) decrease activity at the synapse.
