Name the four kingdoms of Eukarya, and give two characteristics of each?
Answer: The four kingdoms of Eukarya are: Animalia (Metazoa), Plantae, Fungi, and Protista.
1) Animalia:
- They are multicellular organisms that do not possess chlorophyll!
- They are eukaryotic organisms!
2) Plantae:
- They are multicellular organisms with walled and frequently vacuolate eukaryotic cells!
- These contain photosynthetic pigment in plastics!
3) Fungi:
- Fungi are eukaryotic organisms means they have a true nucleus which is enclosed in membranes.
- They are non-vascular organisms!
4) Protista:
- Protists have a nucleus containing their DNA.
- They also have other membrane-bound organelles, such as mitochondria and the endoplasmic reticulum!
HOPE IT HELPS! BRAINLIEST PLEASE!
The four Kingdoms of Eukarya are ; a) Plantae, b) Animalia, c) Protista and Fungi
Kingdoms of Eukarya Characteristics
A) Plantae Possession of vacuolate eukaryotic cells
Presence of chlorophyll
B) Animalia Absence of chlorophyll
Composed of eukaryotic cells
c) Protista Presence of endoplasmic reticulum
Presence of a nucleus containing DNA
D) Fungi Non - vascular organisms
presence of membrane enclosed nucleus
Eukarya is domain composed of kingdoms whose organisms have their nucleus enclosed within a membrane shaped like an envelope. and the organisms that fall within this domain are grouped into four which are , Animals ( Animalia ) , plants( plantae) , protists ( protista ) and Fungi.
Hence we can conclude that the four kingdoms of Eukarya are Plantae, Animalia, Protista and Fungi.

a
Replication is semi-conservative.
b

well for me i don't think so cause you see now a days that parents treat their children equally they don't have to spoil the son and forgets nout the daughter, parents are equally to their kids and in that case their will be no discrimination at all
What drives plate movement?
A. Convection currents in the mantle.
B. Convection currents in the inner core.
C. Convection currents in the crust.
D. Oceanic currents
Answer: The answer is A, convection currents in the mantle.
Explanation: Plate tectonics move because they are carried along by convection currents in the upper mantle of the planet (the mantle is a slowly flowing layer of rock just below Earth's crust). Hot rock just below the surface rises and when it cools and gets heavy, it sinks again.

Why can’t food chains go on forever?
Answer:
Because at some point in that food chain, the energy consumption has it's limit, and the predator will not have anything to hunt it. There is a limited amount of energy in a food chain that can go around, and once you reach the predator, that energy doesn't quite run out but it hits that limit where the chain has to repeat itself.

Optimal activation of transcription of the GAL genes in yeast requires the function of two proteins: Gal4p and Gal11p. Elimination of either protein decreases activation of the GAL promoters. However, inactivation of Gal11p has the additional and dramatic effect of cell lethality. Why might elimination of Gal11p have a greater effect than elimination of Gal4p
Answer:
Gal4p is a transcription factor that targets specific GAL genes, while Gal11p is a core component of the Mediator complex that plays regulatory roles in the expression of many different genes (class II genes) in eukaryotic organisms
Explanation:
The Gal4 transcription factor is one of the most widely studied eukaryotic transcriptional activators capable of activating the expression of galactose-induced genes. Gal4 is well-known to target specific enzymes involved in galactose metabolism: GAL1, GAL7, and GAL10. On the other hand, Gal11p is a key subunit of the evolutionary conserved Mediator complex that binds to the RNA polymerase II (RNAP II) in order to regulate the transcription of class II genes (i.e., genes transcribed by RNAP II).

What molecules in the cell membrane help move molecules from a low to a high concentration gradient?
Answer:
In simple diffusion, small noncharged molecules or lipid soluble molecules pass between the phospholipids to enter or leave the cell, moving from areas of high concentration to areas of low concentration (they move down their concentration gradient).

Analyze Can relative humidity be more
than 100 percent? Explain your answer.
Answer:
Surprisingly, yes, the condition is known as supersaturation. At any given temperature and air pressure, a specific maximum amount of water vapor in the air will produce a relative humidity (RH) of 100 percent. Supersaturated air literally contains more water vapor than is needed to cause saturation.

True breeding plant round seeds (DD) were bred with true breeding smooth
seeds(dd) to produce F1 offspring. F1 offspring were then bred with other F1
offspring. What is the genotypic ratio of the resulting F2 offspring? What is the
phenotypic ratio of the resulting F2 offspring?
Answer:
Genotypic ratio F2 = 1:2:1
Phenotypic ratio F2 = 3:1
Explanation:
In this case, parental genotypes can produce only one type of gamete, i.e., one parent can produce only D gametes, while the other parent can produce only d gametes. Therefore, all F1 generation will be heterozygous (Aa). An F1 hybrid is the first filial generation of offspring obtained from crossing between different parent types. The F1 will produce two gametes (A; a) in a ratio 1:1, thereby the F2 obtained by crossing F1 offspring will have a phenotypic ratio of 3:1 (3 D_; 1 dd) and a genotypic ratio of 1:2:1 (1 AA; 2 Aa; 1 aa).
