Explanation:
A variety of opium poppy (Papaver somniferum L.) having lacerated leaves was crossed with a variety that has normal leaves. All the F1 had lacerated leaves. Two F1 plants were interbred to produce the F2. Of the F2, 249 had lacerated leaves and 16 had normal leaves. Give genotypes for all the plants in the F1, and F2 generations. Explain how lacerate leaves are determined in the opium poppy. (Section 5.2)
Answer:
The correct answer is-
F1 - AaBb (lacerate)
F2 - A_B_; A_bb; and aaB_ (lacerate)
- aabb (normal)
2. Two genes, with a dominant allele at either or both loci.
Explanation:
The given information gives THE following data:
Dominant: Lancerate leaves - AABB
Recessive: normal leaves - aabb
F1 has - all Lacerated leaves - AaBb
F2 by selfing F1:
AB Ab aB ab
AB AABB AABb AaBB AaBb
Ab AABb AAbb AaBb Aabb
aB AaBB AaBb aaBB aaBb
ab AaBb Aabb aaBb aabb
Here, 15/16 = lacerate which is 0.94 which is equal to the value of lacerate given in the question - 249/265 = 0.94
And normal 1/16 = 0.062 is almost same as 16/265 = 0.060
Thus, the genotypes of -
F1 - AaBb (lacerate)
F2 - A_B_; A_bb; and aaB_ (lacerate)
- aabb (normal)

explain why most high pressure air system form at the poles
Answer:
Subsidence
Explanation:
subsidence is a process where cold temperatures in the polar regions cause air to descend to create high pressure it's basically the difference in temperatures that make the pressure so high because hot atoms expand and becomes less dense and rise while cold air contracts and becomes more dense and falls. hope this helps

Answer:
I dont have an answer but what is the actual answer
Explanation:Confused (NO ANSWER)
They will look the same because the plants grown from seeds are genetically identical to one another but not to the mother plant. So, the correct option is (A).
What is Fertilization in plants?Fertilization is defined as the process of sexual reproduction, which occurs after pollination and germination which can be defined as the fusion of male gametes called pollen with female gametes called as ovum to form diploid zygote. It is a physio-chemical process that occurs after pollination of the carpel.
Steps of Fertilization occur in Plants
1. Pollination
2. Germination
3. Fertilization
Fertilization occurs through the pollen tube opening into the ovule through the micropyle and bursting into the embryo sac where the male nucleus fuses with an egg nucleus inside the ovule to form a diploid zygote, which then swells and develops into a fruit. These plants are similar in appearance when grown from seed but with the tuber method they will appear identical but not with the mother.
Thus, they will look the same because the plants grown from seeds are genetically identical to one another but not to the mother plant. So, the correct option is (A).

Why are normally unseen members of the food web, such as soil microorganisms, essential to the nitrogen cycle?
Answer: Why are normally unseen members of the food web, such as soil microorganisms, essential to the nitrogen cycle? ... Since not all organisms can utilize the nitrogen gas directly, these microorganisms convert nitrogen in different nitrogen compounds, such as ammonia, nitrites, and nitrates. In this article we explore how nitrogen is cycled and the important role of microbes in this cycle. ... Nitrogen is required by all living organisms for the synthesis of organic molecules such as amino acids, nucleic acids and proteins. The Earth's atmosphere contains almost 80% nitrogen gas
Bacteria play a central role:
Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates.
Bacteria of decay, which convert decaying nitrogen waste to ammonia.
Nitrifying bacteria, which convert ammonia to nitrates/nitrites.
Denitrifying bacteria, which convert nitrates to nitrogen gas.
Explanation:
Deadly gas. Carbon monoxide is a colorless, odorless gas that binds to hemoglobin at an oxygen-binding site. Indeed, it binds 200 times as tightly as oxygen, accounting for its toxic nature. Even if only one of the four oxygen-binding sites on hemoglobin is occupied by carbon monoxide and the remaining three are bound to oxygen, oxygen is not released. Explain.
Answer:
The binding of carbon monoxide (CO) with hemoglobin leads to an R state even in conditions that should produce the release of oxygen. In consequence, CO-hemoglobin binding shifts the oxygen dissociation curve to the left.
Explanation:
Hemoglobin is a globular protein containing four heme groups that can bind to one oxygen each. This protein (hemoglobin) has two conformational states: the T-state, also known as deoxyhemoglobin (a tense state, where lacks O species), and the R-state, also known as oxyhemoglobin (a relaxed, fully oxygenated state). When carbon monoxide binds to hemoglobin, the protein can not release oxygen, shifting the oxygen dissociation curve -which expresses the percentage of oxygen saturation against the partial pressure of oxygen- to the left. Therefore, under CO-hemoglobin binding, the oxygen level in the tissues is reduced.

Answer:
Myelinated axons utilize fewer voltage-gated channels than unmyelinated axons of the same length and diameter.
Myelinated axons are more energy efficient than unmyelinated axons.
Explanation:
Neurons are cells that specialize in transmitting messages to each other using a type of electrical signal. These signals carry information from outside your body to the brain, while others are the instructions for the various organs, glands and muscles to carry out functions.
Neurons receive these signals from other neighboring neurons through their dendrites. The signal then travels to the soma of the neuron, which is the main body of the cell, and finally travels down the axon to the synapse (space between the end of a neuron and another cell). The axon is a neuronal extension through which the electrical signal travels, extending from the soma to other neurons.
There may be layers of myelin, which consist of a layer of fat, covering the axons and where they have the function of acting as insulators to help keep the electrical signal inside the cell, which makes it move faster increasing the speed of transmission of the nerve impulse.
1) Myelinated axons transmit nerve impulses via continuous conduction. FALSE. In the axon, nodes of Ranvier are found at regular intervals along the length of the axon in the myelin sheath that surrounds it. These are small spaces that expose the axon membrane to the extracellular fluid and serve to allow the nerve impulse to travel faster, in a jumping manner and with less chance of error.
2) Myelinated axons transmit nerve impulses in the same manner as unmyelinated axons. FALSE. In an unmyelinated axon, the movement of voltage across the membrane is due to ion flux that is limited by the time it takes for sodium ions to diffuse into the axon. Myelinated axons conduct faster because they are shorter than unmyelinated axons. In the latter, transmission is continuous but slower.
3) Myelinated axons utilize fewer voltage-gated channels than unmyelinated axons of the same length and diameter. TRUE. The action potential conduction jumps from node to node, thereby they need fewer voltage-gated channels. Unmyelinated axons need voltage-gated channels in along the entire axon.
4) Myelinated axons are more energy efficient than unmyelinated axons. TRUE. The rate at which sodium input through one node can depolarize the axon at the next node is related to the current and capacitance across the membrane. Myelinated axons have faster action potential conduction because it jumps from node to node, thereby they use less energy because they don't have to travel the entire length.
5) Myelinated axons would be unaffected by diseases that attack the CNS. FALSE. For example, Multiple sclerosis (MS) is a demyelinating disease of the CNS in which the immune system attacks the myelin sheath or the cells.
The correct statements are:
Myelinated axons transmit nerve impulses via continuous conduction.Myelinated axons utilize fewer voltage-gated channels than unmyelinated axons of the same length and diameter.Myelinated axons are more energy efficient than unmyelinated axons.Myelinated axons are nerve fibers that are protected by a covering called myelin. In both the central nervous system (CNS) and peripheral nervous system (PNS), oligodendrocytes and specialized cells known as Schwann cells work together to generate the myelin sheath. This sheath is composed of several layers of lipids, which are fatty substances that wrap around the axon in segments, leaving small spaces known as nodes of Ranvier.

Quote: “Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is $tupid.”-Albert
Answer:
It basically means that everyone is a genius in their own way and everyone has their own skills. If you decide to judge someone on what they cannot do (eg. a fish climbing a tree) rather than what they can do, it's gonna make the person feel $tupid their entire life. Not everyone can do the same thing and not everyone has the same abilities. A fish may not be able to climb a tree, but it can swim well. Just like a bee wouldn't be able to swim, but it can fly.
