______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.

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.

A major reason that humans have negatively affected the environment in the past is that humans have
Answer:
Explanation:
attempted to control their population growth
The fact that people have historically prioritized short-term benefits above long-term sustainability is a significant factor in how severely humans have impacted the ecosystem.
Thus, human actions like deforestation, pollution, overfishing, and the burning of fossil fuels have historically been motivated by short-term economic or resource requirements without taking the long-term effects on the environment into account.
The stress on ecosystems and natural resources has grown due to population expansion and rising demand. Unsustainable practises, insufficient regulation, and a lack of awareness have all contributed. To solve these problems, we need to adopt more environmentally conscious behaviors by raising public knowledge of environmental issues.

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.

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.

What hypothesis was validated by using paleo-magnetism?
Question 8 options:
a) subduction
b) hot spots
c) seafloor spreading
Answer:
C). Seafloor spreading.
Explanation:
Paleomagnetism is characterized as the 'study of the account of direction and strength of magnetic fields of the Earth in sediments, rocks, etc.' The hypothesis that was authenticated by using this study would be 'seafloor spreading' by displaying that magnetic reversal as strips of rotating polarity in gradually disseminating seafloor. This description of magnetic stripping by employing paleo-magnetism made the scientists believe that alternate crusts are being frequently made under ocean/sea. Thus, option C is the correct answer.
