In scientific notation, a number is expressed as a value between 1 and 10
multiplied by a power of 10 *
True or false
The answer is true
Explanation:
The definition of scientific notation is: The method of writing very large or small numbers as a product of a number greater than or equal to 1 and less than 10 multiplied by a power of 10
Hope this helped!
The given statement about scientific notation is true which states that in scientific notation, a number is expressed as a value between 1 and 10 multiplied by a power of 10 .
What is scientific notation?Scientific notation is defined as a way of expressing numbers which are too large or too small so that they can be easily written in decimal form. It can be referred to the scientific form or the scientific index form or even the standard form.
Base ten notation is used by scientists, engineers as it helps in simplification of arithmetic operations. It contains the significant figures which include all non-zero numbers , the zeroes between significant digits and zeroes which are needed to be significant.
In scientific notation, the base should always be ten. The exponent should be a non-zero integer and it can be either positive or negative.

Which is the role of the electron transport chain in the process of photosynthesis? A. Cycling electrons between photosystem and photosystem ll B. Adding energy to the electrons that enter photosynthesis C.Carrying electrons from photsystem I1, to photosystem to NADP O D. Removing electrons from the chloroplasts
Answer:
c.
Explanation:
Because youcaring electrons from photosystem II, to photosystem I, to NADP+
I took this test about it hope that helps :D
The role of the electron transport chain in the process of photosynthesis will be carrying electrons from photosystem 1, to photosystem to NADP. The correct option is C.
What is electron transport chain?An electron transport chain is a collection of protein complexes and certain other compounds that donate electrons from electron donors to electron acceptors via redox reactions and couple this electron transfer with the transfer of protons across a membrane.
Photosystems I and II are protein complexes found in the thylakoid membrane.
Their function is to capture high energy electrons from chlorophyll and pass them on to a series of electron carriers before splitting water to form oxygen and hydrogen ions and producing NADPH.
Electron transport contributes to the formation of a proton gradient, which drives ATP production and also stores energy in the reduced coenzyme NADPH.
This energy is used to power the Calvin Cycle, which produces sugar and other carbohydrates.
Thus, the correct option is C.

Write down the secretion, function and deficiency disorders caused by the following gland.
(i) Pancreas (ii) Pituitary (iii) Thyroid gland (iv) Adrenal gland.
Answer:
(I) pancreas - it secretes insulin
it's function is to regulate the sugar levels in blood
if it does not function properly it causes diabetes (sugar)
(ii)pituitary- it secrets growth hormone
it's function is to regulate the growth in human body
if it produces lots of hormone then the body will increase a lot in size known as gigantism
if it produces very less hormone then the body will not increase in size and will be very short known as dwarfism
(III)thyroid gland-it secretes thyroxin
its function is to maintain metabolism growth
lack of iodine makes this gland swell up known as goitre.
(iv)Adrenal gland - it secrets adrenaline
it's function is to help us prepare and respond to stressful situations
because of its malfunction the body does not get enough hormones.

Four of the six kingdoms are compromised of organisms that contain
eukaryotic cells. Which structure in a cell would give you the BEST
evidence that the cell is eukaryotic? *
O Ribosome
O Genetic material
O
Nucleus
O Cell membrane
Answer:
The best evidence that a cell is eukaryotic is the presence of the cell structure called the nucleus.
Explanation:
The most significant difference between eukaryotic and prokaryotic cells is that the former have a nucleus, where they store genetic information in the form of DNA.
The nucleus of eukaryotic cells occupies approximately the center of the cell and is a structure associated with the endomembrane system. Its function is to control cell activity, and its genetic material is duplicated before cell division.
In prokaryotic cells, in the absence of a nucleus, the genetic material is dispersed in the cellular cytoplasm.
Regarding the other options:
Both cell types, eukaryotes and prokaryotes, have ribosomes, genetic material and cell membrane.
______structures are fully functional, show evidence of a common ancestor, and may or may not have
the same function in different species.
Answer:
Homologous
Explanation:
Homologous structures are similar organs or structures that are found in different animals that suggest they come from a common ancestor. This is evidence of evolution.
The structures might not necessarily look identical and might not perform the same function. For example, the flippers of a dolphin, the wings of a bird, the legs of a dog, and the arms of a human are considered homologous structures.
