Answer:
D
Explanation:
34/96= 35%
The mathematical rule of three can be used to take probabilities. In the exposed example, the approximate probability of a moth being black is 35% (Option D).
------------------------
Available data:
47 moths are brown15 moths are yellow34 moths are blackThe total number of individuals in this population equals the addition of brown, yellow, and black individuals.
This total number of individuals equals 100% of the population.
So to get the probability of a moth being black, we can just perform a rule of three.
To do it, we need to get the percentage of black individuals in the current population.
96 moths ------------------------- 100% population
34 black moths ----------------- X= (34 x 100) / 96
=35.41 ≅ 35% of the population
The approximate probability of a moth being black is 35%.

Metaphase is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most condensed and coiled stage (they are at their most condensed in anaphase).
X + H20 → Y + O2(what would be y in this equation ?)
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.

Q.2. Describe the different phases of meiotic prophase – I. Mention the chromosomal events during each stage.
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.

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.
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.
Thus, the correct answer is C.

An ecosystem that retains structure & continues normal functions even when environmental conditions change is?
Resilient
Resistant
Reductive
Reconciled
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.

What type of reproduction involves forming offspring from two
parents?
a Asexual
b Sexual
C Mitosis
int?
d Replication
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.
Hope it helps
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.
