Together, the circulatory and respiratory systems assist eliminate waste carbon dioxide from the tissues and deliver oxygen to the tissue.
The respiratory system is the one that helps to inhale oxygen and exhale carbon dioxide. And the circulatory system is the system that helps to supply oxygen from the lungs to tissues and helps to remove carbon dioxide from the tissue via the lungs. Both these process helps to supply oxygen in this way and helps to remove carbon dioxide as a waste.
First, the oxygen inhaled will be transported to the lungs and this oxygen will be exchanged with the blood that brings the waste (CO₂) from the tissue via the heart. Then, the oxygen will be transported to the heart from where the oxygenated blood will be supplied to the tissues. And the waste from the tissue will be carried via deoxygenated blood.

B. Igf2+/Igf2- and it doesn't matter which parental source the mutated Igf2- comes from.
C. Igf2+/Igf2- but only in female progeny as the Igf2 gene is on the X-chromosome.
D. Igf2+/Igf2+ where neither maternal nor paternal allele is mutated.
E. Igf2+/Igf2- where the mutated Igf2- allele comes from the maternal source.
Igf2+/Igf2-, a genetic condition in which the mutated Igf2-allele is inherited from the father. B. Igf2+/Igf2-, and the parent from whence the mutant Igf2- comes is unimportant.
Whatever happens to a placental after delivery?
The placenta usually breaks from the uterine lining after childbirth. The placenta may still be partially or entirely attached to the uterus when there is placental accreta. This condition happens when the blood vessels and other parts of the placenta encroach too deeply into the uterine lining.
What benefits may you expect if you eat your placenta?
Despite suggestions that eating the placenta can reduce postpartum hemorrhage, increase mood and energy, increase milk production, and provide essential micronutrients like iron, there is no evidence to support any health benefits. You can suffer from placentophagy.

What is the passing of genes from parents to children called?
The passing of genes from parents to children is called heredity.
Inheritance, also called heredity or biological inheritance, is the passing of traits from parents to offspring. Through either asexual or sexual reproduction, progeny cells or organisms acquire the parent's genetic information. Heredity refers to the genetic heritage inherited from our biological parents. More precisely, it is the transference of traits from one generation to the consequent. These traits can be physical, such as eye color, blood type, disease, or behavioral.
In humans, eye color is an example of a genetic trait or Heredity.
A person can inherit the "brown-eyed feature" from either parent. Inherited traits are controlled by genes, and the complete set of genes in an organism's genome is called its genotype.

How is scale type related to diversity
Answer:
Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms. It occurs within a species as well as between species. Ecological diversity
Ecological diversity is the largest scale of biodiversity, and within each ecosystem, there is a great deal of both species and genetic diversity. Species diversity is determined not only by the number of species within a biological community—i.e., species richness—but also by the relative abundance of individuals in that community. … Two communities may be equally rich in species but differ in relative abundance At regional scales, diversity is also increased by speciation and decreased by extinction. These decreases in diversity include those caused by regional extinction events that extirpate species from the region in question but not necessarily from all other regions.Four Types of Biodiversity
Species Diversity. Every ecosystem contains a unique collection of species, all interacting with each other. ...
Genetic Diversity. Genetic diversity describes how closely related the members of one species are in a given ecosystem. ...

In cardiac muscle, the fast depolarization phase of the action potential is the result of
A) decreased membrane permeability to calcium ions.
B) increased membrane permeability to chloride ions.
C) increased membrane permeability to potassium ions.
D) decreased membrane permeability to sodium ions.
E) increased membrane permeability to sodium ions.
E) The increased membrane permeability to sodium ions causes the fast depolarization phase of the action potential in cardiac muscle.
In cardiac muscle cells, what causes the action potential's rapid depolarization phase?An opening of fast sodium channels initiates the depolarization phase of the action potential in muscle and nerve cells. This also occurs in cardiac cells that do not have pacing devices; However, the initial depolarization phase of the action potential is influenced by calcium ions in cardiac pacemaker cells.
What takes place during cardiac muscle depolarization?An electrocardiogram (EKG) is an indirect indicator of heart muscle contraction because contraction of the heart muscles is caused by depolarization of the heart. Without any external stimulus, the heart's cells will depolarize. Automaticity, or autorhythmicity, is the name given to this property of cardiac muscle tissue.

Explanation:
Is co2 essential for photosynthesis,name two ways the validity of this investigation can be ensured
Answer:
Insert a part of the leaf of a destarched plant into a conical flask containing potassium hydroxide. Potassium hydroxide solution absorbs the carbon dioxide gas from the air present in the glass bottle. Leave the plant sunlight. After few hours, perform a starch test to this and another leaf of the same plant.
Conclusion: In this experiment, we can conclude that carbon dioxide is essential for photosynthesis. Both the portion of leaf received the same amount of water, chloroplasts, and sunlight but the half part which was inside the glass bottle did not receive carbon dioxide.
Answer:
Carbon dioxide is essential for the plants to sustain, as it is the carbon fixed from the carbon dioxide during photosynthesis is used for synthesizing glucose. This glucose is then later used during cellular respiration to make ATP, the energy molecule. It is also used by plants as a vital source of carbon to produce a major part of the plant mass.
The importance of carbon dioxide for plants can be proved by a small experiment:
Take two healthy potted plants. Keep them in dark for 2-3 days, so that all the carbon dioxide fixed till that gt used up by the plant. Take the plants and keep both in two separate closed bell jar containers that are air-tight. In one of the jar, keep an open beaker containing potassium hydroxide (KOH) solution along with the plant. KOH can absorb carbon dioxide, so the jar containing KOH is devoid of carbon dioxide. Keep both the jars in sunlight for 4 hours. Pluck the leaves from plants in both jars and remove chlorophyll by boiling in ethanol. Apply iodine solution over the leaves. The leaves of the plant present in the jar without KOH solution turns blue-black color, as the starch in the leaves reacts with iodine. But, the leaves of the plant in the jar with KOH does not change color as in the absence of carbon dioxide the plant cannot produce starch.In most cases, the two major climatic factors affecting the distribution of organisms in terrestrial ecosystems are __________. In most cases, the two major climatic factors affecting the distribution of organisms in terrestrial ecosystems are __________. temperature and sunlight predators and parasites competitors and predators precipitation and temperature wind and precipitation
Answer:
precipitation and temperature
Explanation:
Temperature and water are considered major abiotic factors that affect species distribution in terrestrial ecosystems. The temperature can affect the distribution of terrestrial organisms due to many species maintain a constant internal temperature, while other species maintain a body temperature range that may be very different from the environmental temperature, and therefore they will not be able to carry out their metabolic functions. Hibernation is an adaptation that allows some terrestrial animals to escape temperature fluctuations. Moreover, water is another limiting factor for life, since water is critical for cellular processes. The waxy cuticle is an adaptation that allows terrestrial plants to avoid excessive water loss through transpiration.
Phoebe and Jahiem are working together on an assignment on types of reproduction. They read an article about seedless orange trees. Farmers cut parts of the tree and plant them in the garden to make new trees. Jahiem and Phoebe made the following predictions: Phoebe: I think these trees reproduce asexually and rely on mitosis as there are no seeds to plant. So I predict that all orange trees will be genetically identical to each other and the parents. Jahiem: I think these trees reproduce sexually and depend on meiosis. Plants are multicellular organisms and all multicellular organisms reproduce through meiosis. So I predict that all orange trees will be genetically different from each other and the parents.
Determine who you agree with and explain your reasoning. Be sure to include at least two proofs in your explanation.

Answer:
Technically, both are correct, but I would go with Jahiem.
Explanation:
In terms of how orange trees are normally produced, they usually reproduce asexually, but farmers will graft parts of trees to create new ones. But, normaly trees reproduce sexually.
Write down: An orange tree in the wild is not genetically similar to the one next to it
I agree with Phoebe that orange trees will be genetically identical to each other.
Predictions of PhoebeI think these trees reproduce rely on mitosis as there are no seeds to plant. So I predict that all orange trees will be genetically identical to each other and to their parents.
What are reproduction plants?In reproduction, the plant does not need another gamete to reproduce. For this type of reproduction, parts of the plant are removed to obtain new plants, which is known as a clone. Therefore, what is really used in this type of reproduction is the genetic material of the plant.
Whit this information, we can conclude that i agree with Phoebe that orange trees will be genetically identical to each other.

What causes genetic variation in a population environmental changes?
Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation in a population environmental changes.
Gene flow, or the transfer of genes between several groups of organisms, is another source. The development of new gene combinations through sexual reproduction can also result in genetic variety.
Genetic variation is the variance in DNA sequences among members of a population. Germ cells, such as sperm and eggs, as well as somatic (all other) cells, are subject to variation.
Gene variants, sometimes known as mutations, can cause genetic differences, or a normal process in which genetic information is rearranged as a cell prepares to divide can also cause genetic variations (known as genetic recombination). Different phenotypes can be introduced into an organism by genetic changes that change gene activity or protein function.

What is the process in prophase I that has caused genetic material exchange to take place?
Chromosome crossover is the mechanism by which homologous chromosomes couple up and exchange genetic material during prophase I.
Leptotene, zygotene, pachytene, diplotene, and diakinesis make up prophase I's five stages. Several significant activities, including as the pairing of homologous chromosomes and the reciprocal exchange of genetic material between these homologous chromosomes, take place during these stages in addition to those that take place in mitotic prophase. Prophase I progresses at varying rates according on sex and species.
Until ovulation, several species halt meiosis in the diplotene of prophase I. In humans, oocytes can be stopped in prophase I for decades before swiftly completing meiosis I just before ovulation.
