In a partially diploid F′ exconjugant, there are two alleles for lac (1 and 2) and two alleles for his (3 and 4). The phenotype of this cell is identical to a lac 1 his 4 cell. What is the best interpretation?
Answer:
Explanation:
Lac 1 and his 4 that shows identical phenotype are wild types.
Wild types are the native, the original species or individual of a particular habitat or colony.
Since lac 1 and his 4 are the wild type, lac 2 and his 3 shares the phenotype of Lac 1 and his 4 this because a cross with a wild type will give an individual with a blend of the two gene with phenotype as the wild because they have a dominant gene.
Lac 1 will shows its phenotype when his 4 is also present this is because a cross between the two will give an individual that is phenotypically identical with the parents
Lac 1 and his 4 are dominant.
Which is a cause of chemical weathering
A.gravity
B.acid
C.sunlight
D.wind
Answer:
B. Acid
Explanation:
Acid is the cause of chemical weathering because chemical weathering only occurs when water or whatever mixes with the water is slightly acidic, i.e. salt deposits on the ground mixing with run-off rain water and wearing away at the surrounding environment. Acid rain is also the perfect example of this.
In a murder trial, which person testifying to the jury is classified as an eyewitness?
The medical examiner who found poison in the victim's stomach
An expert discussing evidence collected during an investigation
A defendant's best friend, who was out of town when the crime was committed
A person who claimed to see a car of a certain make/model leaving the scene of a crime
Answer:
A person who claimed to see a car of a certain make/model leaving the scene of a crime.
Explanation:
Key words to the answer:
"See"
"leaving the scene of a crime."
Eyewitnesses have a firsthand glimpse of events that occurred and they usually have to have seen something that has occurred to be considered a eyewitness, in this case the person who saw the Make/Model of the car that left the crime scene has some claims that can be used to find the criminal and also when the eye witness sees the car they can tell which direction it went in to give a bit of a clue(although this depends in certain situations). The eye witness can also be anyone who was anywhere near the crime scene when it happened or even a little bit after it happened.
Answer:
D. A person who claimed to see a car of a certain make/model leaving the scene of a crime
Explanation:
It is D because it would be the closest possible lead for finding who did the crime. Anyone around the time of the murder and anyone going in and out at the time is a suspect, even the eyewitness. If the eyewitness saw someone leaving the location moments before it was reported, that would be suspicious.
(lol among us vibes. it hyped me up for this moment.)
The medical examiner who found poison in the victim's stomach
It would not be this one because they were called after the crime took place, the medical examiner only saw the aftermath of said way to k!ll the person.
An expert discussing evidence collected during an investigation
The expert collected data of the crime scene after it had happened. Otherwise, this would not have been possible. So, they were not an eyewitness since they were not present at the time.
A defendant's best friend, who was out of town when the crime was committed
How would the addressed person out of town see the crime scene? Maybe they were threatened to leave the city? Anyway, it just would not make since for the best friend to be an eyewitness at the time of the crime if they were miles away.
In conservation plowing, why are dead weeds and stalks of the previous year's crop left in the ground?
a. to keep the soil from becoming too fertile
b. to reduce the amount of seed needed for the next year's crop
C. to retain moisture and hold the soil in place
d. to keep more organisms out of the soil
Answer:
to retain moisture and hold the soil in place.
Explanation:
this technology of putting dead plants on the soil under the plants and the area nearing the plants is called mulching.it is helpful in reducing the rate of evaporation and also reduces soil erosion.
Conservation plowing is achieved to minimise soil erosion. Thus, option C is correct.
What is soil erosion?Soil erosion is the deterioration of the topmost layer of soil. The top fertile layer of the soil withers leaving the soil infertile.
It is a gradual naturally occurring phenomenon but can be accelerated with human interventions.
There are many factors responsible for soil erosion:
• Deforestation
• Excessive grazing
• Mining
• Construction work
• Drought and floods
Soil erosion negatively affects the crop yield and also clogs the water bodies. This is therefore harmful for the aquatic species. Dry and barren soil is more prone to floods.
Soil erosion should be minimized as it produces a negative impact on the ecosystem.
Soil erosion can be prevented by planting more number of trees. The roots of the trees help in holding the soil in its place.
Therefore, soil erosion should be checked to preserve the soil fertility.

Consider the following discussion between two students about the cause of the seasons.
Student 1: I know that it's hotter in the summer and colder in the winter, so we must be
closer to the Sun in the summer than in the winter
Student 2: I disagree. Although the distance between Earth and the Sun does change
throughout the year, I don't believe that the seasons and changes in Earth's surface temperature
are caused by the distance between the Sun and Earth. If the seasons were due to the Sun-Earth
distance, then both hemispheres of Earth would have the same seasons at the same time.
Do you agree or disagree with either or both of the students? Explain your reasoning.
Student 2 discussion is true as distance between Earth and the Sun remain same, if the seasons changes were due to the Sun-Earth distance, then both hemispheres of Earth would have the same seasons at the same time.
What is hemisphere ?A hemisphere refers to half of the earth surface, that is divided into northern hemisphere or the southern hemisphere, the cutting of the sphere into two equal halves with one having flat side.
Geometrically the hemisphere is a 3D shape it is half of the sphere is flat and the other side is a circular bowl and it is formed when a sphere is cut at the exact center having two equal hemispheres.
A hemisphere has a surface area which is curved, no edges and no vertices, not a polyhedron, but it has one circular base and one curved surface.
The diameter of a hemisphere is a line type of segment that passes through the center and touches the two opposite pole , the radius of a hemisphere is from the center to a point on the curved surface of the hemisphere.

How are Gymnosperm and Angiosperm plants different?
Answer:
Hey! :D
Explanation:
The gymnosperms, also known as Acrogymnospermae, are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes. The term "gymnosperm" comes from the composite word in Greek: γυμνόσπερμος, literally meaning "naked seeds". The name is based on the unenclosed condition of their seeds. The non-encased condition of their seeds contrasts with the seeds and ovules of flowering plants, which are enclosed within an ovary. Gymnosperm seeds develop either on the surface of scales or leaves, which are often modified to form cones, or solitary as in yew, Torreya, Ginkgo.

Which of the following plant structures allows plants to take in the carbon used in photosynthesis?
Which of the following plant structures allows plants to take in the carbon used in photosynthesis?
roots
vascular bundles or veins
stomata
cuticle
chloroplasts
Answer:
Stomata
Explanation:
Photosynthesis is a unique phenomenon in certain organisms like plants. It is the process whereby they produce their food, in form of an organic compound called GLUCOSE. To synthesize this sugar, plants need a carbon source.
Plants utilize carbon dioxide (CO2), which is an inorganic carbon compound as CARBON SOURCE to synthesize glucose molecule in the process of photosynthesis. This carbon dioxide (carbon) is taken in by the plants via their STOMATA, which is a pore or opening present on their leaves.
The STOMATA opens and closes in order for gaseous exchange to occur i.e. take in CO2 (carbon dioxide), expel O2 (oxygen).
