Answer:
I don't know your reasons on how you would feel about becoming an astrobiologist but this is what I found and my feelings.
Explanation:
The Perseverance twin is called Optimism. This has all of the same electronics as Perseverance and it’s important to have a twin so that they can test things before they operate Perseverance. When they do land on Mars they need the twin to test out all of the sequences and plan that they have for the rover before they send them up to Perseverance on the surface of Mars. Also, if they have a problem with Perseverance it gives them a place to practice how they recover from that problem.
Personally, for me, I would not like to become an astrobiologist. I like science but not that much. I like the simple questions of why and how does it work. I’m not entirely sure that we as humans are meant to be on any other planet except earth. Earth has been here for many many years and seems to reset itself. I don’t care why and will never know why in my lifetime. I’s just not something that I like to considerate doing as a career.
NASA is targeting no earlier than April 8 for the Ingenuity Mars Helicopter to make the first attempt at powered, controlled flight of an aircraft on another planet. Before the 4-pound (1.8-kilogram) rotorcraft can attempt its first flight, however, both it and its team must meet a series of daunting milestones.
Ingenuity remains attached to the belly of NASA’s Perseverance rover, which touched down on Mars Feb. 18. On March 21, the rover deployed the guitar case-shaped graphite composite debris shield that protected Ingenuity during landing. Ingenuity is battery powered and completely sef recharging from the solar panel on the top. The rover currently is in transit to the “airfield” where Ingenuity will attempt to fly. Once deployed, Ingenuity will have 30 Martian days, or sols, (31 Earth days) to conduct its test flight campaign. All data and pictures will be transmitted to Perseverance and then uploaded for all to see.
how does competition limit the amount of individuals in populations?
Explanation:
Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off. This flat upper line on a growth curve is the carrying capacity. The carrying capacity (K) is the maximum population size that can be supported in a particular area without destroying the habitat.

Please help it’s biology!!!!!!
Answer:
25%
Explanation:
If a parent is heterozygous, it has 2 difterent alleles. Both parents are heterozygous for blood type A, so the genotype is AO. A masks the O because A is dominant over O, so A is the blood type.
Create a punnett square to find possible offspring
AA = Blood type A
AO = Blood type A
OO = Blood type O
There is 1 child out of 4 that have blood type O. So to find the percentage divide 1 and 4 and multiply by 100.
1÷4×100 = 25

what is crop rotation
Answer:
MARK ME BRAINLIST
Explanation:
the practice of growing different crops in succession on the same land chiefly to preserve the productive capacity of the soil.
Answer:
Crop rotation was used during the agricultural revolution. It allowed the soil to be healthier and prevented the nutrients from being stripped from the soil. Crop rotation is when your land in separated into different fields for different plants. Usually you would have two or three. One field is left fallow (land that is taken care of, but does not have any crops), and the other one/s are for whatever you choose to plant. Each season you rotate your crops so each field has a turn to be fallow.
Explanation:
Example: you separate your land into three fields. Field 1 has potatoes, field 2 has wheat, and field 3 is fallow. Next season Field 1 is fallow, Field 2 has potatoes, and Field 3 has wheat.

describe how the liver and the pancreas regulate the glucose level in the blood when the glucose level drops
Answer:
ok good question. pancreas is an organ which is found in both the exocrine and endocrine gland that's why sometimes it is called heterocrine. The outer portion of the pancreas(pancreatic islets) secrets the pancreatic juice,insulin and glucagon. let see them deeply: the insulin is a hormone secreted by the pancreas which is used for to lower the blood glucose method in appropriate standard they change it into glycogen and stored in liver. the other one glucagon undergoes a catabolic reaction of the glycogen to the glucose when the blood glucose level is very low so,the liver works in response of lower blood glucose level and the pancreas works in elevated blood glucose level thank you

Unbalanced forces causes acceleration.
A. 1st Law
B. 2nd Law
C. 3rd Law
(will mark brainliest if answers all 3 pls!)
Hope This Helps!
#[tex]AnimePower[/tex]
Explanation:
3.
Answer: Newton's Second Law of Motion
Explantation: Newton's Second Law of Motion is concerned with the effect that unbalanced forces have on motion. An unbalanced force acting on an object causes it to accelerate. The more mass the object has, the more inclined it is to resist any change to its motion.
4.
Answer: The First Law
Explanation: The first Law states that all objects have inertia. The more mass an object has, the greater its inertia and the more force it takes to change its state of motion. The amount of inertia an object has depends on its mass which is roughly the amount of material present in the object.
5:
Answer: Newton's Third Law
Explanation: Newton's Third Law of Motion. Whenever one body exerts a force on a second body, the first body experiences a force that is equal in magnitude and opposite in direction to the force that it exerts.

The changes over time in the inherited traits of a type of organism are ____.
A) growth
B) biogenesis
C) spontaneous generation
OD) evolution
The changes over time in the inherited traits of a type of organism are known as evolution of the species. Thus, the correct option is D.
What is Evolution?Evolution is change in the heritable characteristics of biological populations which are taking place over the successive generations. These characteristics are the expressions of different genes, which are passed on from the parents generation to their offspring during the time of reproduction.
Variation in the genetic material tends to exist within any given population as a result of the genetic mutations and recombination. Evolution in a species occurs when the evolutionary processes such as natural selection and genetic drift act on this variation in species, resulting in certain characteristics which are becoming more common or more rare within a population than other traits.
Therefore, the correct option is D.

Explanation:
Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female sex cell is called the ovum while the male sex cell is called sperm. When these two sex cells come together during fertilization they form the gamete, which is made up of diploid number of chromosomes. Gametes are normally formed through meiosis, during the cell division, the germ cell undergo two fission, which results in four gametes.
