venation in the leaves of dicot plant is: A-.parallel or B- reticulate
Answer:
b. reticulate venation
Explanation:
The arrangement of veins in a leaf is called the venation pattern; monocots have parallel venation, while dicots have reticulate venation. The arrangement of leaves on a stem is known as phyllotaxy; leaves can be classified as either alternate, spiral, opposite, or whorled.
Explain why both arguments are valid in the scenario below.
Situation: Students Claire and Don are debating the future security of food production. Claire feels that it is most
important that food producers focus on producing enough food to keep up with the world's ever-growing population by
using innovations like biotechnology. Don feels that food producers should focus primarily on adopting methods that
are environmentally friendly and safe for human and animal health.
Answer:
Both the arguments are valid.
Explanation:
Claire thinks enough food should should be produced for everyone, because the world's population is rapidly increasing. Don thinks the environment should be kept in mind, because our environment is getting ruined every second. Hence, both arguments are valid.

Two different species mate and produce a zygote. As it starts to develop, it dies due to the genetic differences. What would this be called
Answer:
Postzygotic barrier
Explanation:
The reason why the species died due to genetic difference or genetic variation after the species produced zygote and begins to develop was because of what is called POSTZYGOTIC BARRIER.
POSTZYGOTIC BARRIER is a barrier or otherwise obstacles that does not allow offspring that are fertile and capable of producing a specie to form by preventing the formation after the species has begin to develop which is the development stage thereby making the already formed species to die.

State four ways by which animals living in arid and semi arid areas conserve water
Answer:
Arid or Semi-arid regions are defined as the regions that receive little precipitation.
Four ways by which animals living in arid and semi-arid areas conserve water are as following:
They live in burrows to avoid water leaving their body.Some animals have a thick outer covering which reduces moisture loss, such as Scorpions and wolf spiders.Kidneys of animals in arid or semi-arid regions concentrate urine that helps in less excretion of water.Some animals like Gila monsters and camel have the ability to store water in their body such as in their tails and hump respectively, that can be reabsorbed when needed.1. How does amoeba feed ? (3 points)
there is two question
Answer:
Hey mate here's your answer ⤵️
1. Amoebae typically ingest their food by phagocytosis, extending pseudopods to encircle and engulf live prey or particles of scavenged material. Amoeboid cells do not have a mouth or cytostome, and there is no fixed place on the cell at which phagocytosis normally occurs.
2. Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. ... Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions.

Provide a scientific explanation on how a mutation to the 17th nitrogen base of DNA leads to the formation of sickle cell hemoglobin protein instead of normal hemoglobin protein.
Answer:
Change in DNA leads to change in the structure of the cell.
Explanation:
Mutation in the 17th nitrogen base of DNA leads to the formation of sickle cell hemoglobin protein instead of normal hemoglobin protein because mutation is the sudden change that occur in the genes of a cell which change the genetic makeup of the cell. So when change occur in the DNA, a sickle cell is formed instead of normal hemoglobin. Normal hemoglobin only formed when the no change occur in the nitrogen base of DNA.

The location of cellular respiration
The reactants of cellular respiration
A description of how a building block (for example glucose) is broken down into the products of cellular respiration
The different location of cellular respiration
The products of cellular respiration
What happens to the products of cellular respiration.
The energy in and energy out (the energy flow) of the process of cellular respiration
Answer:
Mitochondria.
Reactants of cellular respiration are glucose and oxygen.
Explanation:
Mitochondria is the location of cellular respiration where glucose is broken down in the presence of oxygen into energy in the form of ATP. When a glucose molecule is broken down with the help of oxygen, it produces energy, carbondioxide gas which is a waste material and water. There are three products of cellular respiration such as energy, carbondioxide and water. Energy is used by the organism in different activities while carbondioxide gas and water are removed from body through breathing. Using of glucose by mitochondria and converted into energy in the form of ATP is the energy flow.

This is for science please help me!
Answer:
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked
Explanation:
If you are ever stuck in a lightning storm while in your car, you should remain in your car. This is because the rubber tires do not allow for the heat and electricity of the lightning to pass through the vehicle. What physical property is this?
malleability
conductivity
density
viscosity
Answer:
Conductivity
Explanation:
Conductivity is the property of a material which describes the ease with which that substance permits or conducts heat and electricity through it.
Materials can either be good, poor or non-conductors.
Good conductors are those materials which allow heat and electricity to pass through them easily. Such materials are useful in making electrical wires and heating vessels. Metals are good conductors of heat and electricity.
Some other materials are poor conductors of heat and electricity as they do not allow heat or electricity to pass through them easily. Examples are air and water.
Some other materials are non-conductors as they do not allow heat and electricity to pass through them. These materials are otherwise known as insulators. They are useful in making things such as pot handles, electrical wire insulators, etc. Examples of insulators are plastic, rubber, wood, etc.
Someone in a car during a thunderstorm is safer inside because the rubber tires do not allow for the heat and electricity of the lightning to pass through the vehicle as it is a non-conductor of heat and electricity.
Dioptría de una persona que puede enfocar hasta 30 cm sin gafas
Answer:
3.33
Explanation:
El término ditropía hace referencia al potencial de refracción de una lente. Por ejemplo, un valor de ditropía de un (1) metro de una lente convergente indica que los rayos que atraviesan dicha lente convergen a un (1) metro de distancia detrás de la lente. De este modo, el valor de dioptría es inverso de la distancia focal expresada en metros. Para calcular el nivel de ditropía se utiliza la siguiente fórmula:
C = 1 / d
donde C equivale al poder de refracción (en unidad de dioptrías) y d equivale a la distancia focal o último punto de enfoque (en metros)
En este caso:
30 centímetros = 0.3 metros >>
C = 1/0.3 m
C = 3.33 dioptrías

New and/or unique data that helps marine biologists gather new information, reach new conclusions, and gain a new understanding of their particular area of study is called
primary source information
secondary source information
immediate source information
cumulative source information
Answer:
primary source information
Explanation:
New and/or unique data that helps marine biologists gather new information, reach new conclusions, and gain a new understanding of their particular area of study is called primary source information.
This is because, a primary source information are gotten from first-hand account or undiluted sources and new data that is not gotten from a secondary source that helps a person or group of persons to reach conclusion is a primary source
Answer: primary source information
