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.

Therefore, we can conclude that agonists are compounds capable of increasing the action of synapse and blockers (antagonists) decrease activity at the synapse.

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.

Answer:always green and pinecones

Explanation:

Answer:1. White blood cells are part of the body's immune system. They help the body fight infection and other diseases.

2. Red blood cells have adaptations that make them suitable for this.

3. The blood would not clot in case of an injury.

4. Blood supplies essential substances and nutrients.

Explanation: 1. White blood cells are able to recognize viruses and/or infectious germs, which is how they fight off disease/sickness. It is also why we have vaccines. Vaccines put either dead or weakened parts of a germ into your body. Then, the white blood cells recognize it and fight it off the next time it enters your body.

2. They contain hemoglobin, a red protein that combines with oxygen. They have no nucleus so they can contain more of the hemoglobin. they are small and flexible so that they can fit through narrow blood vessels.

3. This will lead to excess blood loss and can even lead to the death.

4. Such as as sugar, oxygen, and hormones to our cells. It also carries waste away from the cells, this waste is eventually flushed out of the body in urine, feces, sweat, and lungs.

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.

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.

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).

Renewable source of the energy is defined as the energy collected from renewable sources like wind, water, and light, which can be replenished on the Earth over time.

The given statement is False.

Renewable energy accounts for 20% of the total utility scale. The majority of the energy is derived from non-renewable sources. The non-renewable source of energy cannot be replenished over time and can be exhausted after certain years.

Renewable resources like, wind and waves are used to obtain energy by applying scientific equipment and technologies. The output of renewable sources of energy is lesser as compared to non-renewable sources of energy.

Thus, non-renewable sources of energy account for the majority of energy production.

The urine volume decreased when the solute gradient in the interstitial

space was increased.

The solute gradient in the interstitial space being increased means more

absorption of compounds into the bloodstream and vice versa. When this

occurs, the constituent of urine decreases.

The decrease in the urine components brings about a decrease in its

volume also due to increased absorption taking place.

Phytohormones are responsible for the movement of plant towards stimulus. Auxin is the main phytohormone responsible for gravitropism and phototropism of plants.

Plants are immobile however different parts of the plant show movements in response to the stimulus in the environment. The chemicals present in the plant body which are responsible for these movements are called phytohormones or plant hormones.

Auxins are the main hormones responsible for the cell elongation in plants.  Auxins are responsible for the phototropism (movement of plant parts in response to light) and gravitropism (movement in plants in response to gravity).

Roots of a plant grow downward and exhibit positive gravitropism whereas stems on the other hand, exhibit negative gravitropism since they grow upwards and against the gravity. If you place a plant on its side or even upside down, the stem will curve its way up in response to gravity and auxin is responsible for this movement.

Cells are the basic units of structure and function for living things.

All cells come from pre-existing cells. Also, organisms grow by “adding on more cells” NOT by increasing the size of their cells.

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.

Answer: Angiosperms represent approximately 80 percent of all known living green plants. Examples range from the common dandelion to ancient flowers such as magnolias. Angiosperms also make up the vast majority of all plant foods we eat. (Ex. grains, vegetables, and fruits.) The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and develops into a seed in an enclosed hollow ovary The ovary itself is usually enclosed in a flower, that part of the angiospermous plant that contains the male or female reproductive organs or both. fruits are derived from the maturing floral organs of the angiospermous plant and are therefore characteristic of angiosperms.
