I need help what are plantea and animalia?
Answer: These organasims are both eukaryotic cells, so these 2 cells are capable to produce food by their own. The Plantae include familiar organisms such as trees, herbs, bushes, grasses, vines, ferns, mosses, and green algae. An animalia is one of the basic groups of living things that comprises either all the animals or all the multicellular animals, you can compare that to the plantae or protista.

What is the relative humidity when the dry- bulb temperature is 16°C and the wet-bulb temperature is 14°C?
Answer:
The answer is 80%.
Explanation:
The relative humidity will be 80 %.
What is relative humidity?The amount of water vapor in the air, represented as a proportion of the highest quantity of water vapor the air could contain simultaneously temperature, was known as humidity levels, referred as relative humidity.
Calculation of relative humidity.
It can be calculated as:
Relative humidity = Actual vapor / saturation vapor density × 100
Relative humidity = 14 / 18 × 100
Relative humidity = 0.7777 × 100
Relative humidity = 77%.
Therefore, the relative humidity will be 77 %.

BEST GETS BRAINLIEST.
As The human population increases, so does the consumption of natural resources (fossil fuels, clean water, clean air etc.) What type of impact does this have on our natural ecosystem and environments.
(pls write a paragraph thank u)
Answer: The impact of so many humans on the environment takes two major forms: consumption of resources such as land, food, water, air, fossil fuels and minerals. waste products as a result of consumption such as air and water pollutants, toxic materials and greenhouse gases. Population is growing rapidly, far outpacing the ability of our planet to support it, given current practices. Overpopulation is associated with negative environmental and economic outcomes ranging from the impacts of over-farming, deforestation, and water pollution to eutrophication and global warming. Fossil fuels produce large quantities of carbon dioxide when burned. Carbon emissions trap heat in the atmosphere and lead to climate change. In the United States, the burning of fossil fuels, particularly for the power and transportation sectors, accounts for about three-quarters of our carbon emissions. Population density can have a negative impact on our environment and natural resources. These pressures can lead to deforestation, result in overcrowding, and could lead to the destruction of our planet's delicate ecosystem. Growing populations use large amounts of nonrenewable resources like timber, coal, and oil. Irrigation, for example, uses per calorie less land but more water, fertilizer, and/or capital. The variation of land quality also interacts with development. Population growth increases food demand and therefore the demand for agricultural land. Poverty is believed to be the leading cause of overpopulation. A lack of educational resources, coupled with high death rates leading to higher birth rates, result in impoverished areas seeing large booms in population.

CO2 has been referred to a greenhouse gas because it acts to trap the sun’s heat on our planet like the grase in a greenhouse traps the sun’s heat in the room. what does the graph indicate is the relationship between global tempratures and CO2 concentration
Answer:
a. As CO2 increases, the temperature also increases.
Explanation:
Carbon dioxide (CO2) is an atmospheric molecule produced naturally via respiration or artificially via burning of fossil fuels. CO2, as rightly stated in this question, has been referred to as a greenhouse gas because it acts to trap the sun’s heat on Earth.
Logically, an increase in the amount of greenhouse gas like CO2 released into the atmosphere means an increase in the greenhouse effect or global warming (increase in global air temperature). However, according to the GRAPHICAL REPRESENTATION in this question, an increase in the ppm concentration of CO2 led to an increase in the temperature (°F) of the globe over the years.
As depicted on the graph, at a CO2 concentration of 390ppm, the relative temperature was at over 1°F.

In a density-dependent population, an increase in which of the following will most likely lead to an increase in population density?
Birthrate
Carrying capacity
Death rate
Emigration
Answer:
birthrate
Explanation:
In a density-dependent population, an increase in birthrate will most likely lead to an increase in population density. So, the correct option is A.
What is population density?Population density is the number of people in a given area of land. It primarily applies to people, yet occasionally it also does to other living things. That is a crucial geographic phrase. The amount of people who live in an area per square kilometer, or even other unit of land area, is referred to as population density.
We must divide the population's number by the area's size to determine the population density. Population Density is therefore equal to the number of people divided by the land area. Square miles or square kilometers should be used as the measure of land area. If we need to calculate the density of a relatively small place, then can use square feet or meters.
Therefore, the correct option is A.

How does a new mammoth egg cell get chromosomes from each of the parents?
Answer:
An egg or sperm only has half of the parent's sex chromosome pair. An egg will always have an X chromosome, since the woman's sex chromosome pair only has Xs. Sperm can have either an X chromosome or a Y chromosome. If a sperm with an X chromosome fertilizes the egg, the new cell will have two X chromosomes. One came from the father's sperm and one came from the mother's egg. Since the sex chromosome that is made is XX, the cell will grow into a girl baby.
Explanation:

mixing occur before the chromosomes are sorted into individual sperm or egg cells. Chromosomes from each pair in a mother or father, respectively, make contact and exchange pieces of DNA, creating hybrid chromosomes.
What is chromosome ?A chromosome is a thread-like structure present in the nucleus of cells such as plant, animal and human cells and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).

8. Two heterozygous purple flowered plants are crossed.
What percentage of the offspring are purple?
white?
Answer:
75% chance of purple, 25% of white
Explanation:
Heterozygous means having two different alleles of a gene
This must mean they are Purple dominant and white recessive
This will be represented as Pw
[tex]\left[\begin{array}{ccc} &P&w\\P&PP&Pw\\w&Pw&ww\end{array}\right][/tex]
This, called a punnet square, calculates the probability of the gene outcome. The top Pw represents one parent and the Pw on the left side represent the other.
In the diagram, each combo of letters ( PP, Pw, Pw, ww ) represents a 25% of what gene the offspring will have. PP means it'll be purple, and so does both Pw's. ww means white flowers though because there is no dominant trait and only recessive. This is the only way for a recessive trait to appear in a child.
Therefore there is a 75% chance of the offspring having purple flowers and a 25% chance of the offspring have white flowers.
