Several genes in humans in addition to the ABO gene (I ) give rise to recognizable antigens on the surface of red blood cells. The MN and Rh genes are two examples. The Rh locus can contain either a positive or a negative allele, with positive being dominant to negative. M and N are codominant alleles of the MNgene. Suppose a child's blood type is B MN Rh(neg). The mother's blood type is O N Rh(neg). Check all of the blood types below that the father could have. (Assume no involvement of the Bombay phenotype; everyone is HH.)
a) O M Rh(neg)O M Rh(neg)

A leaf is an above-ground plant organ and it is green. Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close.

The two main functions performed by the leaf are photosynthesis and transpiration. Photosynthesis is the process by which green plants make their food from carbon dioxide and water in the presence of sunlight.

Write the events of the human life cycle in the correct order, starting with what happens right after a pair of gametes comes together?

Answers

Answer: Fertilization occurs, a zygote undergoes mitosis, a baby's cells divide mitotically, meiosis produces sex cells that will participate in fertilization.

Explanation:

Incomplete questions, options are:

Meiotic cell division occurs as the zygote develops into a gamete, meiosis produce the sex cells that will participate in fertilization, a baby grows into an adult through uncountable meiotic divisions, fertilization occurs, a zygote undergoes mitosis, a baby's cells divide mitotically, mitosis produces gametes.

1. Fertilization occurs: Fertilization is the union of a human egg and sperm (male and female gametes), which usually occurs in the fallopian tube. The result is the formation of a zygote or fertilized egg, which initiates the development of the embryo. In this way, the genetic material of both gametes is also fused.

2. A zygote undergoes mitosis: The zygote is the union of the egg and the sperm. Each gamete contributes 23 chromosomes to form the genetic material of the future organism. The zygote starts to divide throught mitosis. Mitosis is a type of cell division that generates two genetically identical daughter cells and occurs in somatic cells (all cells in the body that are not gametes). Eventually, it divides into two blastomeres, then into 4, then into 8, and so on during the passage of the zygote along the fallopian tube towards the uterus. Subsequent divisions of the 12 cells give rise to the morula. Then, the blastocyst is generated, which is an embryo of between 5-7 days of development and is composed of a large number of cells that begin to differentiate.

3. A baby's cells divide mitotically: An embryo is a living being in the early stages of its development, from fertilization until the organism acquires the morphological characteristics of the species. In the specific case of the human being, the term applies until the eighth week after conception (fertilization). Cell divisions for development occur by mitosis. In this way, the embryo will grow and develop, forming tissues and organs through growth thanks to mitotic divisions.

4. Meiosis produces sex cells that will participate in fertilization: Meiosis is a type of cell division that occurs in the gonads for the production of gametes, whereby a diploid cell undergoes two cell divisions, that generates four haploid cells. Thus sperm and oocytes are produced to eventually fuse during reproduction to form a diploid zygote. Meiosis has certain differences from mitosis, since in this type of cell division, the daughter cells created are all genetically distinct from each other and from the parent cell. This is because a crossing over occurs between non-sister chromatids of homologous chromosomes to exchange genetic material. This ensures that each gamete produced has genetic variability.

In human populations of northern European origin, the disorder called hemochromatosis causes excess iron uptake from food and affects one in 200 adults. Among individuals 15 to 50 years old, men are ten times as likely as women to suffer from iron overload. Part A Taking into account this range of ages, what explains this difference

Answers

Answer:

Females of reproductive age lose iron through menstrual blood

Explanation:

Iron is an essential micronutrient involved in the formation of hemoglobin, myoglobin and many enzymatic groups. Moreover, hemochromatosis is a genetically inherited disorder caused by mutations in genes associated with the processes of absorption, transport and storage of iron. The excess of iron is stored in different organs (e.g., liver, heart, pancreas, etc), causing characteristic tissue damage. During each menstrual cycle, women and girls suffer a blood loss of approximately 40 ml, which is associated with an average loss of 1.6 mg of iron. In consequence, it is expected that women of reproductive age (ie, 15–49 years) lose iron during their menstrual periods, thereby avoiding iron overload caused by hemochromatosis.

What happens to proteins with no signal sequence that are made in the cytosol? Question 3 options: They are taken up by lysosomes. They are degraded by proteases. They are returned to their organelle of origin. They are secreted. They remain in the cytosol.

Answers

Answer:

The correct answer is: They remain in the cytosol.

Explanation:

Eukaryotic proteins are made through a process called Translation, which always starts at the cytosol (except for the proteins that are made in the mitochondria).

While Translation is taking place, the peptide that is being synthesized is checked for molecular tags that will lead to a re-routing to another destination: proteins that have an amino sequence called 'signal peptide' will be sent to the endoplasmic reticulum for its translation to continue - the proteins that go this route are meant to be part of the endomembrane system, after that they can be bounded to the ER, the Golgi apparatus or the lysosomes.

Unlike the proteins mentioned before, there are proteins that will have no signal peptide - this means that they are meant to finish Translation in the cytosol. Some of these proteins will acquire a signal tag that will lead them to the nucleus or the mitochondria, for example, but if they don't they will stay permanently in the cytosol to perform their tasks in that place.

Modelizar un ecosistema colocando los niveles tróficos y las relaciones en la red alimentaria

Answers

Answer:

Ejemplo ecosistema y su cadena trófica:  

- Ecosistema: llanura (campo de maíz)  

- Productor primario: plantas de maíz  

- Consumidor primario: Ratones

- Consumidor secundario: Aves rapaces

- Microorganismo descomponedor: bacterias  

Explanation:

En una cadena trófica o cadena alimentaria de un ecosistema, cada nivel obtiene la energía necesaria para sustentar la vida a partir del nivel inmediatamente anterior, mientras que los productores primarios son aquellos organismos que hacen ingresar la energía al ecosistema. Por otra parte, los descomponedores son organismos que se alimentan de los restos de animales y plantas, mediante su descomposición, obteniendo de ellos energía y materia hasta transformarlos en materia inorgánica. En el ejemplo arriba citado, las plantas de maíz representan los productores primarios los cuales producen energía y materia orgánica requerida para sustentar el ecosistema mediante el proceso de fotosíntesis. En segundo lugar, los ratones, como así también otros organismos herbívoros, representan los consumidores primarios los cuales conforman el segundo nivel trófico de la cadena alimentaria. En tercer lugar, los animales carnívoros que se alimentan de consumidores primarios (como por ejemplo, aves rapaces) representan el tercer nivel trófico, y así sucesivamente niveles superiores en el caso que existan depredadores mayores en el ecosistema. Finalmente, bacterias y otros organismos (por ejemplo, hongos, lombrices, algunos insectos, etc) representan los descomponedores los cuales se alimentan de restos orgánicos en descomposición, transformándolos de este modo en compuestos inorgánicos que ingresan nuevamente al ecosistema.

Answers

Answer:

Addaptational changes since they had to adjust to a new environment

The color change of the peppered moths from light to dark after the Industrial Revolution Adaptational changes since they had to adjust to a new environment.

What is  the Industrial Revolution?

During the industrial revolution, the color of bark of the trees became dark. Due to this the predators could easily detect the light colored moths on the dark colored bark of the trees.  

This lead to evolution of light colored moth resulting into dark colored moths through the process of natural selection which made the newly evolved moth population more prominent to the predation attack.  

It became difficult for the predators to trace moth on the tree barks as they became capable of camouflaging against the color of  bark.

Thus, adaptation is the main reason.

15. (d) Al

16. (A) increases

Explanation:

14.

In the reactivity series of metals an element can displace another element from a compound if and only if it is not placed below that metal, as the reactivity of metals decreases when moving from top to bottom- if a metal is placed below Hydrogen it means that it is less reactive than Hydrogen and hence cannot displace Hydrogen from its compound.

All options except A are placed below Hydrogen in the reactivity series, so they wont displace Hydrogen from its compound, but option (a) that is Pb can do so as it is above Hydrogen in the reactivity series.

15.

Al is placed below Mg in the reactivity series and hence cannot displace Mg from its compound.

16.

The reactivity of metals increases down the GROUP.

[CAUTION :- We were talking 'bout REACTIVITY SERIES in the top 2 questions where reactivity decreases down the group, but we're talkin' 'bout GROUPS of the periodic table here, where reactivity increases down the group.]

The size of metals increases down the group causing their valence electrons to drift far from the nucleus so that they can be lost easily. The metals have a property of losing electrons so the more electrons it can lose more will be its reactivity.

Hence, reactivity increases down the group.

Why do all proteins given a negative charge prior to electrophoresis?​

Answers

Answer:

The principle for native gels when Coomassie is not added to the sample is that proteins are separated by a combination of size and charge. The charge in general depends on the number of amino acid residues that bear a positive or negative charge at the pH of the gel. So if running the gel at pH from 8.3 / 8.9, Asp and Glu will be negatively charged, Lys and Arg and His will be protonated and have a positive charge. The N- terminus would have a positive charge while the C terminus would have a negative charge. There might be exceptions depending upon the micro environment of each residue. Native gels can be run at acidic pH as well, to give another way of resolving proteins. Smaller proteins migrate faster than larger proteins. Also, quaternary structure is preserved, so a dimer will run as a dimer so the percentage of total acrylamide monomer used is usually lower than what is used for SDS-PAGE, e.g. 7.5% acrylamide

What are three techniques that can be used to show that the electron transport chain is found on the matrix side of the inner mitochondrial membrane. Select all that apply.

Answers

Answer:

Explanation:

Step 1: Generating a Proton Motive Force

The hydrogen carriers (NADH and FADH2) are oxidised and release high energy electrons and protons

The electrons are transferred to the electron transport chain, which consists of several transmembrane carrier proteins

As electrons pass through the chain, they lose energy – which is used by the chain to pump protons (H+ ions) from the matrix

The accumulation of H+ ions within the intermembrane space creates an electrochemical gradient (or a proton motive force)

Step Two: ATP Synthesis via Chemiosmosis

The proton motive force will cause H+ ions to move down their electrochemical gradient and diffuse back into matrix

This diffusion of protons is called chemiosmosis and is facilitated by the transmembrane enzyme ATP synthase

As the H+ ions move through ATP synthase they trigger the molecular rotation of the enzyme, synthesising ATP

Step Three: Reduction of Oxygen

In order for the electron transport chain to continue functioning, the de-energised electrons must be removed

Oxygen acts as the final electron acceptor, removing the de-energised electrons to prevent the chain from becoming blocked

Oxygen also binds with free protons in the matrix to form water – removing matrix protons maintains the hydrogen gradient

In the absence of oxygen, hydrogen carriers cannot transfer energised electrons to the chain and ATP production is halted
