if a vector not have origin of replication result in what
Answer:
What will be the consequence of not having an origin of replication (ori) in the vector? Explanation: In the case ori is absent, the vector won't be able to replicate
Explanation:
As the replication won't take place, only one of the daughter cells would be having the vector. A colony of transformed colonies won't be obtained.
if a vector does not has the origin of replication result in not doing replication as the unit of replication is Ori.
In the case Ori is absent, the vector may not be capable of replicating. As the replication may not take place, the handiest one of the daughter cells might be having the vector. A colony of converted colonies may not be obtained.
What is transgene?
Of these, the maximum usually used vectors are plasmids. Common to all engineered vectors have a foundation of replication, a multi cloning site, and a selectable marker. The vector itself is normally a DNA series that includes an insert (transgene) and a bigger series that serves as the "backbone" of the vector.
Thus it is clear that if a vector does not have an origin of replication result in nonreplicating.

explain the effects on anaerobic respiration on plants and animals
Answer:
Anaerobic respiration in plants produces ethanol (C2H5OH) whose accumulation may kill the plant, whereas in animals anaerobic respiration produces lactic acid (CH3CH(OH)COOH) that however cannot cause death of animal but lead to minor muscle cramps, but they can be cured with hot water bath or a massage.

List 2 organelles found in an animal cell and explain how those 2 organelles benefit the cell.
Answer:
I chose nucleus and the mitochondria
Explanation:
The nucleus is particularly important among eukaryotic organelles because it is the location of a cell's DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.

Cell includes a cell membrane, cytoplasm and cell organelles. Cell organelles are mitochondria, golgi bodies, nucleus, ribosomes, vacuoles, lysosomes, centrioles, etc.
What are cell organelles?Cell organelles are the structures present in cell that are responsible to carry out necessary processes and maintains homeostasis.
This can include nucleus, mitochondria, golgi bodies, ribosomes, etc.
Nucleus: Nucleus is a membrane bound cell organelle that contain an entangled thread like structure called as chromatin material. This chromatin material condenses at the time of cell division and forms chromosomes. Nucleus also contain nucleolus that helps in formation of ribosomal units. it contains a fluid called as nucleoplasm.Ribosome is the organelle that is involved in formation of protein. It has two subunits i.e. a smaller one and a bigger one. these subunits are joined at the time of protein synthesis and are formed in nucleolus of nucleus.
Thus, these were explanation of two cell organelles along with their explanation.

shown. Check all that apply.
Complete question:
Identify the biotic factors in the environment shown. Check all that apply.
1) people
2) grass
3) rocks in the mountains
4) nylon tent
5) wooden kayak
Answer:
1) people
2) grass
Explanation:
The ecosystem is composed of living and non-living things that interact and depend on each other. These are the biotic and abiotic factors.
Abiotic factors are physical and chemical components of the ecosystem. These are the non-living elements. Biotic factors are all the living components in the ecosystem.Biotic and abiotic factors influence the survival and reproduction of living beings. They are related and in constant interaction. If one of these components is removed, the whole ecosystem will change because its equilibrium has been altered.
Every abiotic component influence organisms and their survival and reproductive rates.
A few examples of the abiotic factors are solar light, minerals, water, air, gases, soil, and humidity.
Examples of biotic factors are plants, animals, insects, microorganisms, etc.
-------------------------------------------------------------------------------------------------------------
The biotic factors of the provided list are:
People, which is a group of individuals composed of cells -which is the basic unit of life-. They grow, reproduce and survive. Grass, as one or many species of vegetables that are also multicellular. They grow, reproduce, and survive.The abiotic factors are:
Rocks, which are non-living things composed mainly of mineralsTent, which is also a non-living thing, is artificially made by humans.In my opinion, the wooden kayak is a gray zone, meaning that it might be confusing. A kayak is an abiotic element with no life and is built by men. But it is constructed of wood. The wood originates in trees that are living beings, they are composed of cells, and they used to be alive. However, when talking about the kayak wood, we are referring to dead tissue. It is not alive anymore. Its cells are dead so, their whole system is not working. It is now composed of minerals and other elements with no life, and it has been modified and processed to build the kayak.
So my opinion is that the wooden kayak is an abiotic factor.

How do you suppose changes in DNA lead to speciation
Answer:
The correct answer is - change in DNA is called mutation which is essential for evolution including speciation.
Explanation:
A mutation is a change in the genetic or hereditary material which is DNA. A mutation is the main reason behind the evolution of the organism or species and speciation can be led by evolution, which takes place by results in the accumulation of many small changes in DNA or genetic changes in a population over a long period of time.
Mutations that change in DNA are required for the evolution process they are the raw material of genetic variation. without changes in hereditary material, there is no speciation or evolution possible.

Which proportion of offspring that are dominant for both traits in would you NOT expect based on Mendel's law of independent assortment
Complete question:
A geneticist crossed fruit flies to determine the phenotypic ratio. The geneticist crossed a fly with blistery wings and spineless bristles (bbss) with a heterozygous fly that had normal wings and normal bristles (BbSs). Which proportion of offspring that are dominant for both traits in would you not expect based on Mendel's law of independent assortment? 1/2 , 4/16, 25% , or 1/4
Answer:
1/2 is the proportion of the offspring that is NOT expected among individuals that are dominant for both traits.
4/16 = 1/4 = 25% of the progeny and the correct expected proportion of individuals that are dominant for both traits.
Explanation:
Available data:
Cross: a fly with blistery wings and spineless bristles with a heterozygous fly that had normal wings and normal bristles Recessive trait: blistery wings and spineless bristlesDominant trait: normal wings and normal bristlesLet us say that:
B is the dominant allele for normal wingsb is the recessive allele for blistery wingsS is the dominant allele for normal bristless is the recessive allele for spineless bristlesParentals) bbss x BbSs

porque los alimentos se oscurecen?(platanos, palta, manzana, papa, etc) respondan pls✋
Answer:
Una enzima es una sustancia, generalmente una proteína, en la célula de un organismo que acelera las reacciones químicas.
Durante el pardeamiento enzimático, una enzima llamada fenolasa y otro compuesto orgánico que se encuentra en las células de la fruta llamados fenoles pasan por una reacción de oxidación cuando se exponen al oxígeno. La fenolasa regula la reacción, convirtiendo los fenoles en melanina.
Por lo general, las enzimas de la fruta están encerradas en tejido. Las enzimas están metidas en sus células, trabajando para madurar la fruta. Pero cuando esas células se descomponen, ya sea por una causa externa como si alguien muerde o corta la fruta o por causas naturales como el envejecimiento, las enzimas se liberan y entran en contacto con el oxígeno, lo que desencadena la reacción química y hace que la fruta se vuelva marrón.

A population of deer has a carrying capacity of 875 deer, with a maximum rate of increase of 1.0 per individual per year. Using the logistic population growth model, what is the approximate population growth rate for a population of 420 deer?
148 deer per year
218 deer per year
307 deer per year
474 deer per year
Answer:
Option B, 218 deer per year
Explanation:
As we know
[tex]\frac{dP}{dt} = kP (1- \frac{P}{K})[/tex]
Where K is the carrying capacity
K is the rate constant
dP/dt is the change in population per unit time and
P is the population
Substituting the given values we get
[tex]\frac{dP}{dt} = k * 420 * (1-\frac{420}{875})\\= 1 *420 * (1-0.48)\\= 218[/tex]
Option B is correct
