where photosynthesis takes place

Answer:

O think it's either B or D

Answer:

The sweat leaves your skin through tiny holes called pores. When the sweat hits the air, the air makes it evaporate (this means it turns from a liquid to a vapor). As the sweat evaporates off your skin, you cool down.

A zygote forms when a sperm fertilizes an egg cell does stage 4 show. So, the correct option is (B).

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).

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.

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.

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.

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.

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.

Answer:

I think that the answer is B

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.

Answer with Explanation:

The "passenger pigeon" used to be North America's most popular bird. Their population even reached 3 billion (or even more). They always traveled together. Their decline in number was noted in the 19th century. People became interested in hunting them for food because they were relatively cheap and tasty . They were also a great source of protein. It was easy to hunt them down although they could fly very fast because their flocks were huge in number. Some people killed them because they didn't want the birds ruining their crops. Their nesting grounds were also disturbed, which ultimately drove them away from the forests. People were overkilling them, and this sped up with the advancement of technology. The number of pigeons killed outnumbered the newborn pigeons, and after decades of hunting them down, their number dwindled with the last one passing away in 1914.

Abstract

The relative contributions of sexual and asexual reproduction to the genetic structure of populations can be difficult to determine for fungi that use a mixture of both types of propagation. Nuclear RFLPs and DNA fingerprints were used to make indirect and direct measures of departures from random mating in a population of the plant pathogenic fungus Mycosphaerella graminicola during the course of an epidemic cycle. DNA fingerprints resolved 617 different genotypes among 673 isolates sampled from a single field over a 3-month period. Only 7% of the isolates represented asexual clones that were found more than once in the sample. The most common clone was found four times. Genotypic diversity averaged 85% of its maximum possible value during the course of the epidemic. Analyses of multilocus structure showed that allelic distributions among RFLP loci were independent. Pairwise comparisons between individual RFLP loci showed that the majority of alleles at these loci were in gametic equilibrium. Though this fungus has the capacity for a significant level of asexual reproduction, each analysis suggested that M. graminicola populations maintain a genetic structure more consistent with random-mating over the course of an epidemic cycle.

The correct answers are:

kitten mushroom bacteria (a)

Bacteria, kitten cactus (d)

Explanation:

The cell theory states that:

a) all living organisms are made up of cells

b) cells are the basic structural and organizational unit of life

c) all cells arise from pre-existing cells.

From the three statements above, all living organisms fall into the categories hence from the list, all the living organisms (Kitten, mushroom, bacteria, and cactus) are made up of cells. While rocks are non-living hence they are not made up of cells.

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

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.
