NEED HELP ASAPPPP!!! PLEASEE
Answer:
1. The meaning of a diploid chromosome is a chromosome that has two complete pairs (sets) of chromosomes (from each parent).
2. Muscle cells, bone cells, blood cells, skin cells, and nerve cells are all diploid. (most cells are minus reproductive ones).
3. Haploid chromosomes are chromosomes that only has only a single set of chromosomes that don't have pairs.
4. Reproductive cells are haploid
7. A dog would have 39 pairs of chromosomes (hence the total 78 chromosomes).
8. A dog's reproductive cell would have half of the diploid cell because it is haploid so it would have 39 chromosomes.
10.The only haploid cell out of the 5 options is the ovum/sperm cell because they are the only reproductive cells (and reproductive cells are always haploid unless they combine to make a pair and form a zygote)
Hope this helps! :D

A track athlete throws a 2kg discus into a field with a velocity of 21m/s. What is the momentum of the discus?
Answer:
Given :
Momentum of disc = 42 kg m/s
Velocity of disc = 21 m/s
To Find :
Mass of the disc.
Solution :
❖ Momentum is defined as the product of mass and it's velocity..
Mathematically, p = m × v
p denotes momentum
m denotes mass
v denoted velocity
➛ It is a vector quantity having both magnitude as well as direction.
➛ It can be positive, negative or zero.
➛ SI unit : kg m/s or N s
By substituting the given values;
➙ p = m × v
➙ 42 = m × 21
➙ m = 42/21
➙ m = 2 kg
∴ Mass of the object is 2 kg.
Knowledge BoosteR :
As per newton's second law of motion, force is measured as the rate of change of linear momentum.
Formula : F = dp / dt
ver a long period of time, flower shapes and color variation have changed as a direct response to attract more pollinators, such as bees and hummingbirds. This is an example of --
Predation
Competition
Parasitism
Commensalism
Answer:
This is an example of parasitism
Ver a long period of time, flower shapes and color variation have changed as a direct response to attract more pollinators, such as bees and hummingbirds. This is an example of Predation. Thus, option A is correct.
What are predators?A predator is a creature that eats all or a portion of the body of its victim, which may be alive or recently deceased. Predators are distinguished from decomposers, such as fungus and bacteria, which break down the remaining remnants of dead species, by the phrase "living or recently killed."
We can confidently classify a lion as a predator if we witness it devouring a zebra. However, the zebra is included in the wide definition as well! Prey for a predator can include both plants and fungi as well as living things.
Additionally, a predator is not required to kill its victim. Instead, it can just remove a part of the prey's body and leave it alive, like a grazing cow or a bloodsucking mosquito. Herbivory is the term for a predator-prey situation in which an animal or insect eats a plant; herbi- stands for plant, and -vory implies eating.
Therefore the correct option is B.
