luster
hardness
0 0 0 0
monetary value

Answer:
hardness
Explanation:
Mohs hardness, rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised (1812) by the German mineralogist Friedrich Mohs. The Mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance of known or defined hardness.

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

La interacción entre soluto y solvente que permite que se forme una disolución se denomina solvatación
Answer:
Verdadero.
Explanation:
En una solución hay un solvente y uno a más solutos. El solvente es el componente que se encuentra en mayor cantidad y que disolverá al soluto. El soluto es el componente que se encuentra en menor cantidad y que se disolverá en el solvente. Para que se forme la disolución, los iones o moléculas presentes en el soluto tienen que ser rodeados por moléculas provenientes del solvente, este proceso se llama solvatación.

flexibility of seasonal production, allowing the grower to target a particular calendar point for bloom time?
A. period from first growth to budding
B. period of dormancy between bloom and grow seasons
C. length of entire bloom period
D. time from breaking dormancy to first growth emerges
*its B*
Answer:
yeah I don't know why but I have the strongest feeling that its B
Explanation:
The elements in the growth of a flowering bulb provides a grower with the greatest flexibility of seasonal production is period of dormancy between bloom and grow seasons.
What are the characteristics of flowering bulb?Bulb is a modified stem that is the resting stage of certain seed plants, particularly perennial monocotyledons. A bulb consists of a relatively large, usually globe-shaped, underground bud with membraneous.
Bulbs can be easily and effectively propagated using a variety of techniques, but always use disease-free material. Try lilies, snowdrops, daffodils, tulips and alliums.
Examples of true bulbs: onion, garlic, allium, daffodil, tulip, amaryllis, grape hyacinth, Dutch hyacinth, Dutch iris, scilla, lily.

In pea plants, the allele for smooth pods (S) is dominant over the allele for constricted pods (s).
Which of the following pairs of terms are correctly matched?
Choose 1 answer:
Ss - phenotype; smooth pod - genotype
SS - genotype; constricted pod - phenotype
SS - phenotype; constricted pod - genotype.
SS - genotype; constricted pod - phenotype
Answer:
ss - genotype; constricted pod - phenotype
Explanation:
trust me Lol
Pea plants having gene control phenotype of pod shape S is dominant having phenotype smooth and phenotype constricted pods having s genotype, hence option d is correct.
What is the difference between genotype and phenotype?Phenotype is a physical observation of a trait which control by agene
and genotype is a genetic observation that can not be seen physically.
The allele which controls the phenotypic character of a plant is called the dominant over the other allele which can not show its expression, the allele is always present in a group but only the dominant will show its expression.
In a pea plant, if the allele for smooth is dominant over the other, it shows expression in allelic combination and masks the expression of constricted pods.
Therefore SS is the genotype and the constricted pod is the
phenotype, hence option d is correct.

Why does estrogen most likely need to increase blood flow in a pregnant woman's body?
so blood can be better filtered
so she can be warmer
O so she can feel calmer
O so blood can reach the fetus
Answer:
So blood can reach the fetus
Explanation:
The blood can reach the fetus so that's why estrogen most likely need to increase blood flow in a pregnant woman's body
What is the function of estrogen?Estrogen refers to a group of hormones produced in the ovaries. The increase in estrogen during pregnancy enables the uterus and placenta to improve vascularization (the formation of blood vessels) transfer nutrients which support the developing baby.
In females, estrogen helps develop and maintain both the reproductive system and female characteristics, such as breasts and pubic hair.

Increase cellular respiration and ATP production
Estivate with a period of dormancy until the warmer weather arrives
Migrate to regions of warmer weather
Slow down its metabolic rate and lower its body temperature

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.

Answer:
I think its manufacuting steel Have a great day
Explanation:
Manufacturing steel is an activity which requires the use of material resources. Thus, the correct option is B.
What are Material resources?Material resources are the materials which are found in the natural world that have many practical use and value for humans. Material resources include wood, glass, metals, edible plants, and plastics. Renewable material resources, like glass, are the resources which can be re-created easily.
Steel is manufactured from iron ore, which contains iron, oxygen and other minerals that occurs in nature. The raw materials for the manufacturing of steel are mined and then transformed into steel using two different processes such as the blast furnace, basic oxygen furnace route, and the electric arc furnace route.

Calculate the gravitational potential energy of a 1,200 kg car at the top of a hill that is 42 m high.
Answer:
Gravitational potential energy = 493,920 J
Explanation:
Given:
Mass of car = 1,200 kg
Height = 42 m
Find:
Gravitational potential energy
Computation:
We know that;
Gravitational acceleration g = 9.8 m/s²
Gravitational potential energy = mgh
Gravitational potential energy = (1,200)(9.8)(42)
Gravitational potential energy = (11,760)(42)
Gravitational potential energy = 493,920 J
