Answer:
As soon as the concentration passed 39, the plants died. Adding to that, I have also found out that the lower the concentration of the sugar, the more the average height becomes.
Explanation:
Plant growth and development are tightly controlled in response to environmental conditions that influence the availability of photosynthetic carbon in the form of sucrose. Trehalose-6-phosphate (T6P), the precursor of trehalas in the biosynthetic pathway, is an important signalling metabolite that is involved in the regulation of plant growth and development in response to carbon availability. In addition to the plant’s own pathway for trehalas synthesis, formation of T6P or trehalas by pathogens can result in the reprogramming of plant metabolism and development. Developmental processes that are regulated by T6P range from embryo development to leaf senescence. Some of these processes are regulated in interaction with phytohormones, such as auxin. A key interacting factor of T6P signalling in response to the environment is the protein kinase sucrose non-fermenting related kinase-1 (SnRK1), whose catalytic activity is inhibited by T6P. SnRK1 is most likely involved in the adjustment of metabolism and growth in response to starvation. The transcription factor bZIP11 has recently been identified as a new player in the T6P/SnRK1 regulatory pathway. By inhibiting SnRK1, T6P promotes biosynthetic reactions. This regulation has important consequences for crop production, for example, in the developing wheat grain and during the growth of potato tubers.

What must happen for most areas on Earth to experience all four seasons?
•The Sun must reach its highest point in the sky.
•The Northern Hemisphere must experience winter.
•The axis must be tilted at a certain angle that."
remains unchanged.
•The north end of Earth's axis must always point away from the Sun.
HELP ON TIMER
Answer:
The correct answer is - The axis must be tilted at a certain angle that." remains unchanged.
Explanation:
On the earth there ae many seasons but there are four major season, winter, summer, spring and autumn. The main reason that leads to all four season is the tilt of the sun at a specific angle that remain unchanged which leads to change in the distance to the sun at specific time of the year which result in different rays of sun the part. So, whatever hemisphere or part tilted towards the sun leads to different season for instance:
North pole tilted towards the sun - summer in northern hemisphere
south pole tilted towards the sun - winter in northern hemisphere

Convert from kilometers to centimeters to determine the distance from the sun. Use the scale 25,000,000km = 1cm.
Mercury- 57.91 million kilometers
Venus - 108.2 million kilometers
Earth - 150 million kilometers
Mars- 227.9 million kilometers
Jupiter- 778.5 million kilometers
Saturn- 1.434 billion kilometers
Uranus- 2.871 billion kilometers
Neptune - 4.495 billion kilometers
Answer: See Below
Explanation:
25,000,000km = 1cm
In other words 25 million km = 1 cm
Mercury- 57.91 million kilometers
57.91 million km * 1 cm/ 25 million km = 57.91/ 25 cm = 2.3164 cm
Venus - 108.2 million kilometers
108.2 million km * 1 cm/ 25 million km = 108.2 /25 cm =4.328 cm
Earth - 150 million kilometers
150 million km * 1 cm/ 25 million km =150/25 cm = 6 cm
Mars- 227.9 million kilometers
227 .9 million km * 1 cm/ 25 million km = 227.9/25 cm =9.116 cm
Jupiter- 778.5 million kilometers
778.5 km * 1 cm/ 25 million km = 778.5/25 cm =31.14 cm
Saturn- 1.434 billion kilometers
1.434 billion * 1000 million/1 billion = 1434 million
= 1434 million km * 1 cm/ 25 million km =1434/25 cm =57.36 cm
Uranus- 2.871 billion kilometers
2.871 billion * 1000 million/1 billion = 2871 million
2871 million km * 1 cm/ 25 million km =2871/25 cm =114.84 cm
Neptune - 4.495 billion kilometers
4.495 billion * 1000 million/1 billion = 4495million
4495 million km * 1 cm/ 25 million km =4495/25 cm =179.8 cm

Why is oxygen such an important input for cellular respiration?
Answer:
Oxygen is important because it makes aerobic respiration possible by accepting electrons from the transport chain in the mitochondria. Sometimes oxygen is unavailable in some of your muscle cells (typically during heavy exercise); at times like these, the muscle cells will temporarily revert to lactic acid fermentation, which yields far less energy.
Explanation:
Answer:
Well oxygen is important for cellular respiration when it comes to humans and some other animals but for some other organisms and cells they don't require oxygen.
Explanation: Why we would say oxygen is important for the cellular respiration of humans is because if you take it away this can destroy the whole process of cellular respiration which can harm the humans. Metabolic poisons or Rat poisons work in a similar way by disrupting process done by enzymes in cellular respiration so just like that taking oxygen will disrupt cellular respiration in the human harming them or even causing death as parts of the cell such as the mitochondria use it in fact one of the parts of the cycle for making ATP for some animals requires oxygen such as the Krebs cycle.

1. Describe the relationship of the location of the prostate gland to the urinary tract. Why is this significant
Answer:
The prostate is a gland of the male urogenital system, it is located below the bladder, in front of the rectum and is crossed by the urethra. In this way the urine leaves the bladder, crossing the prostate, until it is expelled. One of the most important functions of this gland is to provide nutrients for the maturation of the sperm.
Explanation:
The prostate gland is made up of 30-50 glands that empty their contents into the prostatic urethra (the tube that connects the prostate gland with the bladder urethra). Most cancers develop in the peripheral area of the gland, that is, the outermost area of it and is the one that can be felt with the finger. The entire organ is surrounded by a fibrous prostatic capsule.The prostate because it is located below the bladder and starting from it, is crossed by the urethra which is a tube that carries urine from the bladder to the outside. In turn, the prostate is crossed by another tube that comes from the seminal vesicles, which are glands whose mission is to provide nutritional elements to the semen and the vas deferens, which are tubes that start from the testicles and mainly lead the sperm to the outside.

One hundred percent of Peruvian Indians tested have blood type O. How can this type be so prevalent if it is based on the presence of two recessive alleles (ii)?
Answer:
Due to the presence of dominant allele.
Explanation:
This type of blood is prevalent even if two recessive alleles are present because the allele of blood type O is dominant as compared to other two recessive allele. Due to dominance of the blood type O, the blood type of next generation will also be type O. we know that only the dominant allele will appear in the offspring so that's why the Peruvian Indians have blood type O.
