Answer:
1,2 × 10⁹ : 1
Explanation:
In fact, the average male will produce roughly 525 billion sperm cells over a lifetime and shed at least one billion of them per month. A healthy adult male can release between 40 million and 1.2 billion sperm cells in a single ejaculation.
Explanation:
Therefore, a standard sperm to egg ratio of 1 × 105 sperm per egg is recommended for fertilization in Atlantic cod. At the 1 × 103:1, 5 × 103:1, and 1 × 104:1 sperm to egg ratios maximum fertilization occurred after 30 min sperm to egg contact time.

What are the five necessary components of a DNA synthesis reaction?
Answer:
They are: substrates, template, primer and enzymes. Four deoxyribonucleotide triphosphates (dNTP's) are required for DNA synthesis (note the only difference between deoxyribonucleotides and ribonucleotides is the absence of an OH group at position 2' on the ribose ring). These are dATP, dGTP, dTTP and dCTP.
spanish:
Ellos son: sustratos, plantilla, imprimación y enzimas. Se requieren cuatro desoxirribonucleótidos trifosfatos (dNTP) para la síntesis de ADN (tenga en cuenta que la única diferencia entre desoxirribonucleótidos y ribonucleótidos es la ausencia de un grupo OH en la posición 2 'en el anillo de ribosa).

En que consisten las siguientes interacciones bioticas de las relaciones entre organismos: DEPREDACION, PARASITISMO, MUTUALISMO, COOPERACION, SIMBIOSIS, COMPETENCIA, COMENSALISMO, AMENSALISMO
Answer:
La depredación implica la interacción entre un depredador y una presa. El parasitismo ocurre entre 2 organismos diferentes donde un parásito se alimenta del huésped hasta que el huésped es destruido, el mutualismo ocurre es una forma de relación donde ambos organismos de diferentes especies se benefician. La cooperación se produce cuando los organismos trabajan juntos como un equipo para lograr objetivos comunes, como derribar a un gran depredador. En la simbiosis ocurre en diferentes organismos donde ambos se benefician o uno se beneficia o ninguno se beneficia a medida que interactúan. La competencia es la capacidad de un organismo para prosperar en entornos difíciles. El comensalismo es un tipo de relación que ocurre entre organismos donde uno se beneficia y el otro no se ve perjudicado. El amensalismo ocurre entre diferentes especies de organismos en una relación donde uno es destruido y el otro prospera.
Explanation:
La depredación ocurre en la cadena alimentaria donde los organismos más pequeños son consumidos por los más grandes en la cadena alimentaria. El depredador no puede sobrevivir si hay una reducción en la población de presas. Un ejemplo se ve en un león y un ciervo. En el parasitismo, el parásito solo puede sobrevivir cuando el huésped está vivo. Una vez que el huésped muere, el parásito muere con él. El parásito deriva todo su sustento del huésped hasta que el huésped es destruido. Ejemplo de garrapatas en perros. En mutualismo, ambos organismos de diferentes especies en relación obtienen los mismos beneficios. Un ejemplo es el del pájaro picador y la cebra, donde el pájaro picador obtiene su alimento de la cebra y la cebra controla sus plagas. La cooperación se produce entre las mismas especies que trabajan juntas para derribar presas más grandes. Se observa un ejemplo entre las hormigas que derriban una cucaracha. En el caso de la simbiosis, podría ser uno de los 4 tipos: comensalismo, mutualismo, parasitismo o endo / ectosimbiosis. Aquí los organismos de diferentes especies trabajan para lograr objetivos divergentes que a veces se ayudan mutuamente y otras veces se daña. La competencia se ve cuando un organismo posee características especiales que lo ayudan a sobrevivir en ambientes hostiles. Por ejemplo, algunas bacterias poseen cápsulas que les ayudan a almacenar alimentos y sobrevivir largos períodos de deshidratación, así como la presencia de determinantes de resistencia a los antibióticos que pueden ayudarlos a sobrevivir a un ataque de antibióticos. En el comensalismo, una especie vive de otra, pero la otra no sufre daños. Un ejemplo típico son las aves que viven en huecos de árboles. En el amensalismo, la presencia de una especie de organismo inhibe el crecimiento de otro. Un ejemplo es el de las malas hierbas en una granja de maíz. Las malas hierbas ahogan la planta hasta que se destruye para que puedan prosperar.

A human baby is born with one X chromosome and one Y chromosome. What
must be true about this baby?
A. The baby is female
B. The baby is haploid
C. The baby is prokaryotic
D. The baby is male
Answer: d) the baby is male
Explanation: Ovules contain X chromosomes whereas sperms come in two types: one type contains x chromosome and the other contains Y chromosome.
When a sperm containing X chromosome fertilises with an ova, the zygote will have two X chromosomes. This zygote would develop into a female child. When a sperm containing Y chromosome fertilises with an ova, the zygote will have one X and one Y chromosome. This zygote would develop into a male child.

Answer: the baby is male
Explanation: female babies are born with 2 X chromosomes. Haploid babies have a one set of unpaired chromosomes. It’s impossible for a baby to have an X and Y chromosome pair and be prokaryotic. Males have one X chromosome and one Y chromosome, so it has to be male.

(c) find the longest interval during which no tree-cutting samples occurred. what is the first year that no tree-cutting samples occurred in that interval?
Answer:
Longest interval during which no tree-cutting sample occurred: 9 years (1203 AD - 1212 AD)
First year in that interval: 1203 AD
Explanation:
Lets complete the question first.
Q) A study uses tree rings to determine the year in which a tree was cut. The data is shown in the leaf and stem diagram in the ATTACHMENT.
The three digits number in the left column represents centuries and decades AD. The numbers on the right represents the years.
For example, consider the first input in the diagram
119 | 5 6
which means it represents 2 samples.
1195 AD, 1196 AD.
The longest interval with no tree-cutting samples is found from 1203 AD to 1212 AD.

Discuss the interconnections of the cardiovascular system with each of the other major body systems introduced. Give specific examples of these interactions and explain their effect on homeostatic balance.
The correct answer to this open question is the following.
The interconnections of the cardiovascular system with each of the other major body systems is of the utmost importance for the health of the human body. The circulatory system's main function is to take blood to all the cells of our body. The instant the heart stops bombing blood to all the cells, organs, glands, and systems, the body stops its vital functions. The Circulatory system has a direct relation to the optimal operation of other systems such as the Respiratory system, the Reproductive system, the Digestive system, the Skeletal system, the Muscular system, the Lymphatic system, the Nervous system, and the Endocrine system.

which statement provides the best argument against making major changes to the atmosphere to help protect Earth's resources
Answer:
The options are
A. There will be less soil and dust in the air as construction increases.
B. The atmosphere will improve as more people move to large cities.
C. Making major changes to the atmosphere can be a costly process.
D. It is more important to protect land and water resources than the atmosphere.
The answer is C. Making major changes to the atmosphere can be a costly process.
Explanation:
Making major changes to the atmosphere to the atmosphere to help protect Earth's resources is costly because no one knows the effects of what the changes will have when effected. Another angle is effecting the changes will be a very expensive one as the atmosphere is very large and will be difficult having it happen.
This however validates making major changes to the atmosphere can be a costly process as the right option.

Explanation:
A and B are biotic in nature, C, D, and E are abiotic in nature. In an open system, A produces D and E while B could not produce anything rather depend totally on the D and E produced by A. As the number of A increases, it favours the growth of B, the production of D and E also enhances the growth and development of B.
Answer:
A: Plants
B: Consumers
C: Sun
D: Oxygen
E: food
Explanation:
Abiotic factors refer to non-living things int he ecosystem, whereas the biotic factors are the living things in the environment.
A, in this case, is referring to the plants in the ecosystem, the producers. Plants produce D and E, that is, oxygen and food respectively. B are the consumers in the environment, the herbivores in particular that feed on the plants and rely on it as the only food source. C refers to the sun as the source of light energy for the plants.
