One person is pushing a cart with a force of 300 units to the right. Another person is
pushing on the same cart with a force of 450 units to the left. What is the unbalanced net
force acting on the cart?
150 units to the left
O 150 units to the right
750 units to the right
O Option 4
Answer:
The answer is 150 units to the left.
Explanation:
You start with the bigger number and subtract it because they ´re going opposite directions. It goes to the left because your net force will go in that same direction with the bigger number.
450 - 300 = 150 units to the left

A species of jungle chicken is codominant for red and white feathers. What color would be expressed in the offspring represented by the missing square below if R represents the allele for red feathers and W for white feathers ?
Answer:
i mean i think is white cuz it’s dominate WW
Explanation:
so don’t know
A species of jungle chicken is characterized by its codominance of red and white feathers, so when both the green parents are crossed then, the mission offspring will be white in color, that is, WW, and this is recessive (option c).
What is the significance of the genetic cross and codominance?Codominance is the type of cross in which neither alleles suppresses the other, implying that both are co-dominantly expressed, as in the case of the crossing of the green parents, where there is one RR is the production of the dominant trait that is red. Two will be green; this is the co-dominance, and the other is white, represented by WW.
Hence, a species of jungle chicken is characterized by its codominance of red and white feathers, so when both the green parents are crossed then, the mission offspring will be white in color, that is, WW, and this is recessive (option c).

The Hadley Cell is set up by rising air over the equator. It begins with warming of air surrounding the equator, which
creates a large region of lower surface pressures. This belt of equatorial low pressure causes air to be drawn together
and the warm, moist air over the equator rises upward, to the top of the troposphere. Once the warm air rises, where
does it go?
A)
It circulates back down in the latitudes at the equator
B)
It spreads out north and south and travels toward the poles.
Eliminati
It cools and sinks back down toward Earth at about 300 latitude.
D)
It creates circulation cells in the upper atmosphere that move north and
south across Earth's latitudes.
Once the warm air rises, it cools and sinks back down toward Earth at about 300 latitude. Thus option C is correct.
What is Hadley Cell?Hadley cell is defined as the air rising close to the equator, flowing poleward at a height of 10 to 15 kilometers above the earth's surface, falling in the subtropics, and then returning equatorward close to the surface.
It can also be defined as the low-latitude overturning circulations, where air rises at the equator and sinks at a latitude of around 30 degrees.
The tropical easterlies and trade winds are produced by the Hadley cell, a large-scale atmospheric circulation pattern in the tropics, which is brought on by warm air rising in the tropics, flowing toward the poles, then cooling off, falling, and flowing back toward the equator.
Thus once the warm air rises, it cools and sinks back down toward Earth at about 300 latitude. Thus option C is correct.

how do the size and shape of human canines compare with chimp canines
Answer:
Human canines are blunt and small in size, while chimps have big and sharp canines.
Explanation:
Chimps' mouths are larger than humans' mouths. Chimps have a flat palate; and bigger and sharper canines than humans. Also, there is a space between these teeth and the teeth at the front of the mouth. On the other hand, humans' mouths are smaller, which leads to smaller and less sharp canines, and there is no space between these teeth and the teeth at the front of the mouth.
Answer:
Humans are more circular and wide, while chimpanzees are longer and skinnier

A single cell of testis divides to produce:
a. 4 sperms.
b. 6 sperms.
c. 2 sperms.
d. a single sperm.
Answer:
Each primary spermatocytes goes through the first meiotic division, meiosis I, to produce two secondary spermatocytes, each with 23 chromosomes (haploid). Just prior to this division, the genetic material is replicated so that each chromosome consists of two strands, called chromatids, that are joined by a centromere.
Answer:
Assertion In the testis, spermatogenesis occurs in the seminiferous tubules and testosterone secretion takes place from the Sertoli cells. Reason Testosterone brings growth and maturation of secondary s3x organs and also the development of accessory s3x characters.

how does mRNA get out of the nucleus
Answer: mRNA moves through pores in the nuclear membrane
Explanation: nuclear membrane pores permit the passage of mRNA, but only after processing within the nucleus. The non-coding parts of the RNA are deleted (introns), the 5’ end capped to prevent premature degradation, and a string of A nucleotides added at the 3’ end (improves stability).

This table list traits of four types of vertebrates. Each trait first appeared in a common ancestor of the animals that evolved later. These traits are used to build a branching diagram.
Based on the information in the table, which animal belongs in the spot labeled A on the branching diagram?
A.Tuna
B.Frog
C.Robin
D.Shark
The outgroup is the most distant group that appears in a branching diagram. It shares a common ancestor with the rest of the groups but expresses none of the traits they express. In this example, sharks belong to the outgroup A. Option D.
What is an outgroup?
In a phylogenetic trees or cladograms, the most distant group is called outgroup. It shares no traits or characters with the lineages of interest that compose the ingroup.
You can compare the outgroup with the ingroup to determine the evolutive relationship and which characters are primitive or derived.
Even though the outgroup shares a common ancestor with the ingroup, this is placed far away in evolution, making the outgroup to be the taxonomic group less related to the other lineages.
The lineages in the ingroup share another common ancestor that is more recent in history.
In the exposed example, A is the outgroup. It shares a common ancestor with the other groups, but express none of the characters mentioned in the tree. This is because it evolved before these charecters emerged.
Option D is correct. Sharks belong to the A group. As you can see in the table, it has none of the mentioned traits. It does not have a bony skeleton, lungs, amniotic eggs, or feathers.
