What does the chloroplast produce during the light independent reactions of photosynthesis?
Answer: Glucose
The chloroplast during photosynthesis produce glucose under the light independent reactions. This happens due to some chemical reactions that convert carbon dioxide and other compounds into glucose. The process of these chemical reactions is called Calvin cycle, where it has three phases of light independent reactions, which are carbon fixation, reduction reactions and ribulose 1,5-bisphosphate (RuBP) regeneration. These reactions occurs in the stroma, the fluid filled area of chloroplast outside the thylakoid membrane.
Which is the best definition of miscarriage? deliberate end of pregnancy before 20 weeks spontaneous end of pregnancy after 20 weeks spontaneous end of pregnancy before 20 weeks NextReset
Answer:
Spontaneous end of pregnancy before 20 weeks.
Explanation:
Abortion is a very traumatic situation in a woman's life and is characterized by an early termination of pregnancy before 20 weeks. Abortion or, more correctly, abortion is the early termination of a pregnancy before the fetus can survive outside the mother's body. Abortion can occur intentionally or completely spontaneously, in both cases being a painful process for the woman living in this moment.
The World Health Organization (WHO) presents some criteria for the termination of pregnancy to be considered an abortion. According to WHO, abortion is considered interruption before 20 weeks of gestation, in which case the fetus is usually less than 500 g. When the fetus is removed under these conditions it is unable to survive outside the mother's womb.
The complex of proteins and dna in a nondividing cell is called
Answer:
chromatin
Explanation:
Chromatin (from the Greek chromatos, color) is a collection of strands, each formed by a long DNA molecule associated with histone molecules, a special type of protein. These wires are the chromosomes.
The chromatin filaments intersect eucromatin points with heterochromatin points. These two varieties of chromatin proceed differently according to the time of cell life. In the interphase, the segments of heterochromatin appear to be spiraled (similar to a telephone cord), while the segments of eurochromatin are distended. Thus, the chromonemas appear thicker and more colored at the heterochromatin points and are so thin that they are almost imperceptible at the level of the eurochromatin points.

Temperature is read by measuring the liquid in the thermometer using the scale on the thermometer. When the temperature rises, the liquid in the thermometer . When the temperature drops, the liquid in the thermometer .
Answer:
When the temperature rises, the liquid in the thermometer expands. When the temperature drops, the liquid in the thermometer contracts.
Explanation:
The thermometer is filled with a liquid called mercury. Increase in temperature makes this liquid to expand. The expanded liquid occupies most of the space in the thermometer causing a rise in its level.
On the other hand, a drop in temperature makes the liquid to contract. The contracted liquid has less volume and occupies lesser space in thermometer. This causes a drop in the level of liquid in thermometer.
Which characteristic was first to appear as hominids diverged from a common ancestor?
The first characteristic to appear as hominids diverged from their common ancestor was bipedalism, preceding other traits like large brain development and changes in facial and dental anatomy.
As hominids diverged from their common ancestor, the first characteristic to appear was bipedalism. This trait evolved before other human-like traits such as encephalization, or the development of a large brain, and the evolution of flat faces and small teeth. The transition to bipedal locomotion involved anatomical changes such as longer legs, changes in spinal curvature, and the development of arches in the feet, which aided in energy conservation and balance when walking. Rather than appearing all at once, these traits exhibited mosaic evolution, appearing in the fossil record at different times.
Most dissolved carbon in the ocean is used to form which structure in marine organisms?
Answer: Carbon dioxide reaches through atmosphere in the water and moves down inside the water. Some marine structure make food by the process photosynthesis by the help of carbon dioxide and sunlight.
Carbon dioxide is present in the form of bicarbonate ions and hydrogen ions. The increase in H ions decreases the pH of the water.Some of the hydrogen combines with carbonate to form more bicarbonate ions decreasing the amount of carbonate ions.Many marine organisms combine calcium and carbonate to form the exoskeleton, shells and other structures.

In your own words, describe how the properties of an ocean wave determine the motion of a surfer on the wave?
The height of the waves determine the motion of a surfer on the wave.
Waves typically have a range of heights. If the height of the waves increased, the surfer would rise to a greater height and fall to a lower depth on the waves, and the radius of the circle in which the surfer moves would increase. Same as if the height of the waves decreased, the surfer would rise to a lower height.

Activation of the sympathetic division of the autonomic nervous system produces _____ in heart rate, and activation of the parasympathetic division produces _____.
a.increases, additional increases in heart rate
b.increases, decreases in heart rate
c.decreases, increases in blood pressure
d.decreases, additional decreases in heart rate
Final answer:
Activation of the sympathetic division of the autonomic nervous system increases heart rate for a 'fight or flight' response, while activation of the parasympathetic division decreases heart rate, supporting a 'rest and digest' state.
Explanation:
The autonomic nervous system, which includes the sympathetic and parasympathetic divisions, plays a crucial role in regulating the heart rate among other functions. Activation of the sympathetic division of the autonomic nervous system increases heart rate, preparing the body for 'fight or flight'. Conversely, activation of the parasympathetic division leads to a decrease in heart rate, facilitating a 'rest and digest' state. The sympathetic nerves release norepinephrine, which binds to adrenergic receptors causing an increase in heart rate. Parasympathetic nerves release acetylcholine, which binds to muscarinic receptors, resulting in a slowing of the heart rate.

soil that contains large quantities of calcium was most likely formed by the weathering of
Limestone
Limestone are form of sedimentary rocks mainly compose of skeletal fragments from marine fragment such as molluscs, forams and corals. Aragonite and mineral calcites are the major minerals found in limestone which were different crystal forms of calcium carbonate. Also, they are an organic sedimentary rock which forms from the accumulation of coral, algal, shell and facal debris.
Soils rich in calcium are commonly a result of the weathering of rocks like limestone, dolomite, or transported soils enriched with calcium through the process of calcification.
Soil that contains large quantities of calcium was most likely formed by the weathering of rocks containing limestone, dolomite, or gypsum (CaSO4). Such soils can also result from transported soil formed from weathered components that have been transported by water, wind, or ice to a different area. Moreover, soils in warm, semi-arid environments, usually under grassland vegetation, are subjected to a process called calcification, where the B horizon of the soil is enriched with calcium carbonate precipitated from water moving through the soil.
