Explanation:
If each parent has two sets of genes and chromosomes why do their offspring receive only one set from each parent
Answer:
Because we are diploid humans, and we have 2 chromosomes per set. We get one set from our mother, and one from out father. Each of the sets from our parents are haploid (1 ), so together they are a diploid(2) set. I can go into depth more with meiosis if you need.

Human embryonic development is the development and formation of the human embryo. It is characterized by the process of cell division and cellular differentiation of the embryo that occurs during the early stages of development. In biological terms, the development of the human body entails growth from a one-celled zygote to an adult human being. Choose ALL of the statements that correctly describe stages in human embryology and gestation.
The normal period of gestation is about 40 weeks.
The germinal stage refers to the time from fertilization through the development of the early embryo until implantation is completed in the uterus in about 21 days.
The stages of human development include, in order: zygote, blastocyst, embryo, and fetus
A blastocyst, if untouched and allowed to remain implanted, will eventually develop into a morula.
Changes to the form of the embryo come from differentiation and growth.
The statements that correctly describe gestation are: the normal period of gestation is about 40 weeks; the stages of this process include: zygote, blastocyst, embryo, and fetus; and changes to the form of the embryo come from differentiation and growth.
The gestation period in humans lasts about 40 weeks and comprises different stages and processes from conception until birth. The main stages of this process include:
Zygote: Fertilized ovum.Blastocyst: Cluster of cells that is the result of the zygote going through cell division.Embryo: Unborn human that is still developing, usually before the 8th week of gestation.Fetus: Unborn human in development after the 8th week of gestation.Moreover, this process implies differentiation as cells specialize for specific functions, for example, muscle cells or nerve cells, and growth as the number of cells increases and therefore the embryo or fetus increases in size.

1. There are two birds that live in the same type of tree, same climate, and eat the same type of fruit. However, one is nocturnal (awake at night) and the other is diurnal (awake in the day). Explain why these two birds are considered to have different niches.
Answer: different species
Explanation: They live in the same community like a Gouldian finch and a Double-Barred finch but are different species
However, one is nocturnal (awake at night) and the other is diurnal (awake in the day) as it consist of different species and they live in the same community like a Gouldian finch and a Double-Barred finch but are different species.
What shows the low light in the evening?The hours of low light in the evening shows that it would be when humans would be most at risk from dangers. Species might make sense to seek shelter during this period.
As a result of their divergent evolutionary paths, various species have evolved in various ways to adapt to their habitats. The reason a certain species is nocturnal or diurnal has a variety of different potential causes. Perhaps at night, when light levels are low, when humans would be most exposed to dangers. The decision to seek sanctuary during this time may therefore be justified. Considering the various predatory dangers that mice and rats encounter, it is possible that being active at night reduces the threat posed by predators like birds who utilize their visual senses to identify prey.
Therefore, However, one is nocturnal (awake at night) and the other is diurnal (awake in the day) as it consist of different species and they live in the same community like a Gouldian finch and a Double-Barred finch but are different species.

Which of the following must be true in order for natural selection to occur?
Group of answer choices
There must be variation in traits in the population
The trait must cause the individual to evolve
The trait must have no other advantage in fitness
The trait must be for the good of the species
The trait must be heritable
The trait must advance the goal of evolution
Answer:
For natural selection to occur, it is true that there must be genetic variation in the population.
Explanation:
According to evolution, natural selection implies the changes that occur in the genotype of a species, due to the effect of environmental factors, and which guarantee its survival through adaptive evolution.
For natural selection to occur, three fundamental conditions must exist:
A trait that can be inherited from one generation to another.
The trait is subject to variability between subjects of the same species.
Genetic variability can determine the possibility of reproductive success and survival.
Therefore, a necessary factor for natural selection to occur is that genetic variability exists in the population.
For natural selection to occur :-
There must be variation in traits in the population.The trait must cause the individual to evolve.The trait must be for the good of the species.The trait must be heritable.The trait must advance the goal of evolution.What is Evolution?It is the change in the characteristics of a species over several generation.It relies on the process of natural selection.

Which option distinguishes what a commodities trader would do with the information in the following scenario?
A heat wave is expected to hit the central United States and cause a drought that will kill off many wheat plants.
sell off wheat supplies immediately at their highest price
immediately buy futures contracts at their current prices
cancel all options on future sales of wheat
wait until the heat wave to make wheat purchases
The commodities trader would immediately buy futures contracts at their current prices. The correct option is C.
Thus, a commodities trader would probably predict a decline in wheat supply if they learned about an anticipated heat wave and drought that may affect wheat plants. They would then buy futures contracts at their present levels in response.
By taking this move, the trader is able to protect himself against prospective price rises brought on by the decreased supply of wheat by securing the right to purchase wheat at a certain price in the future. The trader may be able to take advantage of the predicted market conditions before the impact of the heat wave is fully felt by purchasing futures contracts.
Thus, the ideal selection is option C.

Explanation:
Weathering is the process by which rocks disintegrate into smaller fragments. Rock expands (with heat) and contracts (with cold) in response to temperature changes.
What is Weathering?Weathering is the deterioration of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms.
Rock responds to temperature fluctuations by expanding with heat and contracting with cold. This is frequently observed with a weathering process known as Frost wedging, in which water freezes and thaws inside rock fissures. Salt wedging is a different type of weathering in which the salt that is left over after water evaporates can exert pressure on rock fissures.
Thus, Weathering is defined as the process by which rocks disintegrate into smaller fragments.
