Why does the body produce more urine on a cold day rather than a hot day if the same amount of
water is consumed?
Explanation:
During summer when the surrounding temperature is high, we lose water in the form of sweat, direct evaporation considerably. Hence kidneys retain water for maintaining fluidity of the blood and less urine is formed.
But during winter, the surrounding temperature will be very low. There will not be any sweating, no evaporation losses. Moreover to keep the body temperature constant, the blood capillaries in the skin get constricted and the blood pressure is increased. The result is that our body gets warmed up. In order to maintain the blood pressure normal, the excess water along with the wastes is excreted mostly in the form of urine. This is the reason for more urine out put and frequent urination under very cool conditions and in winter.
Explain what the greenhouse effect is, use diagrams if you wish.
Include:
-Radiation from the sun absorbs earths heat
-Some emitted
-Trapped by the greenhouse
Answer:
See the answer below
Explanation:
The greenhouse effect refers to the heating effects produced by the earth's atmosphere on the planet as a result of the atmosphere absorbing reflected radiation from the sun by the earth.
The earth's atmosphere is a blanket of gases, some of which are referred to as greenhouse gases. These gases have the capacity to trap radiations coming from the sun that is reflected by the ground layer of the earth. Thus, they produce a warming effect on the earth.
A bulk of the radiation coming from the sun is reflected back into space by the earth's stratosphere. The small percentage that passes through are dispersed in different directions and some of them pass through the atmospheric blanket to reach the ground layer of the earth. While some are absorbed by the ground itself, some are emitted back into the atmosphere where the greenhouse gases trap a large portion and prevent them from escaping back into space.
This leads to the warming of the earth and the entire phenomenon is referred to as the greenhouse effect.

The law of conservation of mass was created in 1789 by a French chemist, Antoine Lavoisier. ... For example, when wood burns, the mass of the soot, ashes, and gases, equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant

What are the 3 common characteristics of planets? Describe one of the characteristics of one of the planets in our solar system
Answer:
The solar system is host to two broad categories of planets. The four closest to the sun — Mercury, Venus, Earth and Mars — are the terrestrial planets. They have rocky surfaces enclosed by relatively shallow atmospheres. The gas and ice giants — Jupiter, Saturn, Uranus and Neptune — are outliers. They are much larger than the terrestrial planets, but their cores are small and icy. Most of their size is formed by a combination of gases that become denser and hotter as you get closer to the core. Scientists count eight planets overall. Pluto was reclassified as a dwarf planet in 2006.

Iron rich deposits that formed about 2 billion years ago have red layers. Layers formed before then were not red. The red layers formed when oxygen made during photosynthesis reacted with iron molecules in the ocean. The oxidized iron formed layers of sedimentary rock
. Which BEST summarizes this phenomenon?
A. The lithosphere changed the atmosphere. B. The hydrosphere change the atmosphere.
C. The atmosphere change the biosphere.
D. The biosphere change the lithosphere
Answer:
D. The biosphere change the lithosphere
Explanation:
The red formed due to oxygen which is produced by plants in the process of photosynthesis. This oxygen then reacted with iron atom and formed oxidized iron layers of sedimentary rock. So here plants are responsible for the formation of these layers and we considered plants as part of biosphere so we can say that biosphere is responsible for the change of lithosphere.

Examples of stimuli are the strong smell of a woman's perfume, the sour taste of a lemon, pinching your skin, dimming the lights in a room, and having your back massaged. The correct options are a, b, c, d, and e.
What are stimuli?Humoral stimuli, hormonal stimuli, and neurological stimuli are the three basic types of stimuli that cause the endocrine glands to produce and release hormones.
With changes in the concentration of extracellular fluids, the humoral stimulus governs hormone release.
The strong smell stimuli the sense organs and sour taste stimuli our tongue and pinching in the skin gives stimuli to obtain that someone pinched pour skin
The neural stimuli allow hormone production straight from the glands.
Therefore, the correct options are a, b, c, d, and e.

megakaryocytes are huge cells found in red bone marrow that extend long tendrils into blood sinusoids. The flow of blood breaks off small portions of those tendrils creating the formed element known as
Answer:
Platelet
Explanation:
In 1906 James Homer Wright established that platelets, seen as hyaline bodies or vacuoles, are formed in the cytoplasm of megakaryocytes in the bone marrow, which then disintegrate and pass as platelets into the circulation. Megakaryocytes are cells of the myeloid lineage. They originate platelets (or thrombocytes) by cleaving parts of their enormous cytoplasm directly into a sinusoid vessel. The function of platelets is to form thrombi to prevent blood loss in small blood vessel ruptures.

A. A spore grows into a mature gamete-producing plant.
B. A zygote forms when a sperm fertilizes an egg cell.
C. A gamete-producing fern plant is flat and shaped like a heart.
D. A mature spore-producing fern plant has fronds and produces
spores.
A zygote forms when a sperm fertilizes an egg cell does stage 4 show. So, the correct option is (B).
What is Zygote?After pollination, the male gametes present in the pollen grains move into the ovules and fuse with the female gametes where the single cell resulting from this fusion is called the zygote. This process is called fertilization.
In flowering plants, a haploid gamete called an egg cell and a sperm cell first fuse to form a diploid cell called a zygote. The zygote is the progenitor stem cell that gives rise to all embryonic and post-embryonic tissues and organs.
Thus, a zygote forms when a sperm fertilizes an egg cell does stage 4 show. So, the correct option is (B).

a Glucose is broken down to pyruvate.
b Respiration requiring oxygen occurs in the
mitochondria.
.
Most ATP is produced during glycolysis and the
Krebs cycle.
d The Krebs cycle occurs directly after glycolysis.
Answer: a. Glucose is broken down to pyruvate.
b. Respiration requiring oxygen occurs in the mitochondria.
Explanation:
Cellular respiration can be defined as the process in which oxidation of food occurs in the mitochondria and energy is released as ATP. The glucose which is six carbon molecule is most common substrate for oxidation and it is converted into pyruvate which is a three carbon molecule. This is occurs in aerobic cellular respiration. During cellular respiration 30+ ATP molecules are produced which is comparatively more than glycolysis and Kreb's cycle.

According to the base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine, T is not paired with G, hence option C is correct.
What is base-pairing in DNA?Because it is RNA, there is no complementary base pairing between the bases adenine and thymine in DNA. Uracil, which has a structure remarkably similar to that of thymine, is present in place of thymine.
Base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine structure of DNA is created by the binding of these base pairs
Although they keep the two strands of DNA together, they are not strong enough to withstand replication.
Therefore, the base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine, hence option C is correct.
