Answer:
All systems work together to stabilize the body.
Explanation:
Certain systems work with each other in order to maintain homeostasis, which is essential for the body. For example, when blood circulates through the digestive system, it picks up nutrients absorbed by the body during its last meal. Additionally, blood carries oxygen taken in by the lungs. The circulatory system works with the respiratory system here to distribute oxygen to other parts of the body.

What is a DNA probe?
Answer:
In molecular biology, a hybridization probe is a fragment of DNA or RNA of variable length which can be radioactively or fluorescently labeled. It can then be used in DNA or RNA samples to detect the presence of nucleotide substances that are complementary to the sequence in the probe.DNA probes are stretches of single-stranded DNA used to detect the presence of complementary nucleic acid sequences (target sequences) by hybridization. DNA probes are usually labelled, for example with radioisotopes, epitopes, biotin or fluorophores to enable their detection.

En biología molecular, una sonda de hibridación es un fragmento de ADN o ARN de longitud variable que puede marcarse de forma radiactiva o fluorescente. Luego puede usarse en muestras de ADN o ARN para detectar la presencia de sustancias nucleotídicas que son complementarias a la secuencia en la sonda. Las sondas de ADN son tramos de ADN monocatenario utilizados para detectar la presencia de secuencias complementarias de ácido nucleico (secuencias diana) por hibridación Las sondas de ADN generalmente están marcadas, por ejemplo, con radioisótopos, epítopos, biotina o fluoróforos para permitir su detección.

A plant tissue made of tubular cells stacked to form structures called tubes.
A. xylem
B. cambium
C. phloem
Answer:
C
Explanation:
Xylem are stronger and thicker tubes than the Phloem, and the Xylem are meant to bring nutrients and water from the roots too the leaves!
Phloem are much smaller, and much more brittle than the Xylem, and they also have a different job. These are meant to take the glucose made from photosynthesis and move it to the rest of the plant. These are made up of tubular cells, creating a vascular system.

What are some ways that the nitrogen cycle overlaps with or influences the oxygen and carbon cycles?
Are any of these interactions between the cycles positive?
Answer:
Nitrification happens when soil organisms change over ammonium into nitrate. Much of the cover between the carbon cycle and the nitrogen cycle happens within the soil, in forms conducted by soil organisms. Organisms break down supplements, construct modern compounds for their possess development, and die.

why is nectar important for insects?
Answer:
Nectar is important for insects because.. Nectar is an ecologically important item, the sugar source for honey. It is also useful in agriculture and horticulture because the adult stages of some predatory insects feed on nectar. For example, the social wasp species Apoica flavissima relies on nectar as a primary food source. In turn, these wasps then hunt agricultural pest insects as food for their young.

Sheila weighs 60 kg and is riding a bike. Her momentum on the bike is 340 kg • m/s. The bike hits a rock, which stops it completely and throws Sheila forward onto the pavement. If there is no net force on the system, what is Sheila’s velocity immediately after she is thrown from the bike?
Answer:
5.7 m/s
Explanation:
The computation of Sheila 's velocity right after she gets thrown out of the bike is shown below:
1) The Physical principle: conservation of momentum.
If there is no net external force operating on a system, so the system's total momentum is conserved
The momentum, p, is a vector magnitude that is determined as the product of the mass by the velocity:
P = mv.
2) Taking into account therefore that there is no net force on the device, Sheila and the momentum of the bike are the identical pre and post collision.
Based on this, the calculation is as follows
Momentum before the collision:
[tex]P_1 = (mass\ of\ Sheila + mass\ of\ the\ bike) \times velocity[/tex]
[tex]P_1 = (60kg + m) \times v_1[/tex]
= 340 kg m/s
Now Momentum after the collision:
[tex]P_2 = mass\ of\ sheila \times velocity\ of\ Sheila + mass\ of\ the\ bike \times velocity\ of\ the\ bike[/tex]
[tex]P_2 = 60kg \times v_2 + m \times 0 = 60kg \times v_2[/tex]
[tex]P_1 = P_2[/tex]
[tex]= (60kg + m) \times v_1[/tex]
[tex]= 60kg \times v_2[/tex]
[tex]= 340 kg .\ m/s[/tex]
[tex]= 60kg \times v_2[/tex]
[tex]v_2 = \frac{340\ kg .\ m/s }{60\ kg}[/tex]
= 5.7 m/s
The velocity of Sheila immediately after she is thrown from the bike is 5.67 m/s.
The given parameters;
mass of Sheila, m = 60 kgmomentum of Sheila, P = 340 kg.m/sThe velocity of Sheila immediately after she is thrown from the bike is calculated as follows;
P = mv
where;
v is the velocity Sheila
[tex]v = \frac{P}{m} \\\\v = \frac{340}{60} \\\\v = 5.67 \ m/s[/tex]
Thus, the velocity of Sheila immediately after she is thrown from the bike is 5.67 m/s.

i am generally found both inside and outside of the nucleus {in eukaryotic cells} is it DNA O RNA ?
Answer: RNA
Explanation:
Nearly all the RNA found in a typical eukaryotic cell is rRNA. Transfer-messenger RNA (tmRNA) is found in many bacteria and plastids.
What is generally found both inside and outside of the nucleus of a eukaryotic cell is ; RNA
RNA is formed in eukaryotic cells when DNA contained in the nucleus of the cell is transcribed/synthesized. The transcribed RNA is then moved out of the nucleus into the cytoplasm.
The RNA contained in the cytoplasm is later transcribed into protein in the cytoplasm of the cells . therefore RNA is contained both inside and outside the nucleus of a eukaryotic cell.
Hence we can conclude that what is generally found inside and outside the nucleus of a eukaryotic cell is RNA
