Answer:
Low power objective lens
Explanation:
On a standard microscope with three objectives on the nosepiece, the lowest objective lens is usually 4x magnification.
The high power objective is usually 40x magnification.
Hope this helps!
The piece that contains a low-power magnifying lens (4x) is a low-power objective..
A low power objective is a short-length objective lens, which is often is useful for aligning the microscope.A low power objective can be used to examine and identify large specimens or many smaller specimens. The total magnification obtained from a low-power magnifying lens (4x) when combined with a 10x eyepiece lens is a 40x magnification.In conclusion, the piece that contains a low-power magnifying lens (4x) is a low-power objective.

Answer: It supports that the leftover radiation (neat) is spread uniformly (same) throughout the universe
Explanation:
The Big Bang theory predicts that the early universe was a very hot place and that as it expands, the gas within it cools. Thus the universe should be filled with radiation that is literally the remnant heat left over from the Big Bang, called the “cosmic microwave background", or CMB.

Which of the following has a positive charge and a mass of one amu?
Answer:
a proton
Explanation:
It is found in the nucleus of an atom and has a positive charge with 1 atomic mass unit
According to the host, which of these is true of the reaction between ammonia and hydrochloric acid?
A.
It is considered an acid-base reaction because there is proton donation and acceptance.
B.
It is not considered an acid-base reaction because there is no hydroxide present in the base.
C.
It is not considered an acid-base reaction even though there is proton donation and acceptance.
Answer:
A.
Explanation:
In water, the reaction between ammonia (NH3) and Hydrochloric Acid (HCl) is an example of acid-base chemistry. By its chemical nature, the nitrogen in ammonia prefers to be attached to four hydrogens rather than the three it has, so it receives them from the hydrogen from HCl

Base your answers to parts a and b on the diagram below and on your knowledge of biology. Part A: explain why process 2 is important to sexual production. Part B: identify processes 1 and 3. State one difference between the cells produced by process 1 and the cells produced by Process 3.
Answer:
1. Please find the explanation to Part A below
2. Process 1 is meiosis while process 3 is cell division
3. Cells produced in process 1 are haploid while cells produced in process 3 are diploid
Explanation:
PART A:
The process 2 described in the attached image is called FERTILIZATION. It is the process whereby male gamete (sperm) unites with the female gamete (egg) to yield a ZYGOTE. This process of fertilization is important to sexual reproduction because it is the way the diploid state of an organism is restored after haploid gametes must have been formed via meiosis. In other words, haploid (n) sperm and egg unites during fertilization to yield a DIPLOID ZYGOTE (2n).
PART B:
- Process 1 in this attached image depicts MEIOSIS, which is the process whereby haploid daughter cells (gametes) are formed from the division of a diploid cell. Meiosis reduces the chromosome number of a cell by half.
- Process 3 is CELL DIVISION. The zygote formed from fertilization (process 2) undergoes series of cell division to produce the EMBRYO.
PART C:
The cells produced in process 1 (meiosis) are HAPLOID i.e. contains one set of chromosomes while the cells produced in process 3 (cell division) are DIPLOID i.e. contains two set of chromosomes
Which statement best describes the importance of the cell cycle to the growth of organisms?
A- the cell cycle determine the sequencing in DNA, which regulates the order that proteins are created.
B- the cell cycle determines which cells die and which cells continue to replicate repeatedly.
C-The cell cycle carefully regulates the growth and division of cells, helping organisms grow and heal properly.
D-The cell cycle controls the types of nutrients that enter and leave the cell.
Answer:
I think it is B
The he statement best describes the importance of the cell cycle to the growth of organisms- C-The cell cycle carefully regulates the growth and division of cells, helping organisms grow and heal properly.
Cell cycle or cell-divisionis the series of events that take place in a cell leading to its division and duplication of its DNA to produce two daughter cellsmitosis is part of the cell cycle and cells undergoing mitosis in multicellular organisms are used for the development and growthcells divide is to reproduce and to repair themselves of any damage.Thus, the statement best describes the importance of the cell cycle to the growth of organisms- C-The cell cycle carefully regulates the growth and division of cells, helping organisms grow and heal properly.

What is the percentage of agar required to prepared a solid medium?
Answer:
1-2%
Agar is typically used in a final concentration of 1-2% for solidifying culture media. Smaller quantities (0.05-0.5%) are used in media for motility studies (0.5% w/v) and for growth of anaerobes (0.1%) and microaerophiles.
