CORRECT QUESTION -How many types of enzyme does pancreas secrete and name them!
CORRECT SOLUTION -The pancreas consist of exocrine glands that produces enzymes making digestion playing an important role . The enzymes made by the pancreas include :
Pancreatic proteases (such as trypsin and chymotrypsin) - which help to digest proteins .Pancreatic amylase - which helps to digest sugars (carbohydrates) .Pancreatic lipase - which helps to digest fat .━━━━━━━━━━━━━━━━━━━━━━━
X + H20 → Y + O2(what would be y in this equation ?)
Answers
Answer:
y. 2. • CxHy + O2 → x CO2 + y/2 H2O. Combustion Problem. Erythrose is an important mono-saccharide that is used in chemical synthesis. It contains Carbon.
Explanation:
In the chemical equation X + H₂O → Y + O₂, Y represents the product of the chemical reaction, here Y is the glucose, and this X is carbon dioxide, and this is a reaction of the photosynthesis.
What is photosynthesis?During photosynthesis, the energy from light is used to split water molecules into oxygen and hydrogen ions. The oxygen is released into the atmosphere as a waste product, while the hydrogen ions are used to create a chemical gradient across the thylakoid membrane within the chloroplast. This gradient is then used to power the creation of ATP, the energy currency of cells, as well as to reduce carbon dioxide to form organic molecules, such as glucose. The overall equation for photosynthesis is:
6 CO₂ + 6 H₂O + light energy → C₆H₁₂O₆ + 6 O₂
Hence, In the chemical equation X + H₂O → Y + O₂, Y represents the product of the chemical reaction; here, Y is the glucose.

why are vitamins important to enzymes and what this relationship is called?
Answers
The activity of some enzymes requires vitamins. This is because vitamin derivatives contribute to the biochemical mechanisms of these enzymes.

Q.2. Describe the different phases of meiotic prophase – I. Mention the chromosomal events during each stage.
Answers
Prophase-I occurs over a long duration and involves several complicated changes in meiotic cell division. It is important because genetic recombineiion and variation in sexually reproducing organism occurs due to the events of this phase.
EXPLANATION:❈ Leptotene —
➥ The chromatin network opens out and threads become clear.
➥ The chromosomes are thin, slender and long.
➥ Chromosome number is diploid.
❈ Zygotene —
➥ Corresponding chromosomes become intimately associated.
➥ The process of pairing is known as synapse. It is so exact that pairing is not merely between corresponding chromosomes but between corresponding individual units.
➥ The chromosomes become shorter and thicker.
❈ Pachytene or Pachynema —
➥ The synaptic chromosomes become very intimately associated.
➥ The pair of chromosomes becomes short and thick.
➥ Crossing over occurs at this stage. Chiasmata are clearly seen.
❈ Diplotene —
➥ Homologous chromosomes start separating from one another.
➥ Chiasmata tend to slip out of the chromosomes. This is known as terminalisation of chiasmata.
➥ Chromosomes start separating out but the separation is not complete.
➥ Nuclear membrane and nucleolus start disappearing.
❈ Diakinesis —
➥ The bivalents condense further and get randomly distributed.
➥ The separation of paired chromosomes is almost complete.
➥ Terminalisation of chiasmata is almost complete.
➥ Nuclear membrane and nucleolus disappear.

An ecosystem that retains structure & continues normal functions even when environmental conditions change is?
Resilient
Resistant
Reductive
Reconciled
Answers
Answer:
Resistant
Explanation:
A good aspect of the ecosystem can either be resistant or resilient when there is a disturbance or a form of deviation from the regular occurrence in the ecosystem structure, function, or both.
For an ecosystem to be resistant means it maintains structures and goes on with normal functions despite the disturbance or alteration in environmental circumstances.
Hence, in this case, an ecosystem that retains the structure and continues normal functions even when environmental conditions change is RESISTANT.

A sexually mature seahorse can produce thousands of offspring. What is the BEST reason overproduction of offspring by marine organisms is considered to be a reproductive advantage?
It increases competition.
It decreases competition.
It contributes to the organism’s biological success.
It causes stress on the environment which will apply stress to the creature to adapt.
Answers
Answer: D
Explanation:
There are large number of predators present in marine environment. Overproduction of offspring contributes the biological success of the organism.
What is overproduction?Overproduction is referred to the production of large number of species which can be physically supported by ecosystem.
Overproduction support survival of the fittest, by improving the genetic line.
Since the predators are more so, only that organism will survive who can adapt according to the that. This can contributes in organism's biological success.

Answers
Answer:
Sexual
Explanation:
Sexual reproduction involves two parents and produces offspring that are genetically unique. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.

Answer: Sexual, I believe.
Explanation:
If it were Asexual, it'd only involve one parent. Mitosis has daughter cells have the same number of chromosomes as parent cells (heavy emphasis on cells as in plural cells.) And replication is just copying a cell.
