Sickle cell anemia is a mutation that results in abnormally shaped blood cells. Which two of the following molecules are changed as a result of this mutation?
lipids
mRNA
Sugars
Pigments
Protein
Answers
Sickle cell anemia is caused by a single letter mutation so transcription will lead to synthesis of a different mRNA molecule . The different mRNA molecule will lead to a different protein where a single amio acid is different(there is valine instead of glutamic acid)
Instinct or learned behavior?
A lizard becoming ill after eating a poisonous insect?
Answers
The response of a lizard becoming ill after eating a poisonous insect is most likely an instinctual behaviour rather than a learned behavior.
What is instinctual behaviour?Instinctual behavior, also known as innate behavior, is a type of behavior that is genetically programmed in an organism and does not require prior learning or experience. These behaviors are often complex and are typically exhibited in response to specific environmental stimuli or triggers. Instincts are common in animals and are often associated with survival and reproduction.
Examples of instinctual behavior in animals include migration, hibernation, nest building, territoriality, and courtship displays. In many cases, instinctual behavior is triggered by external environmental cues such as changes in light, temperature, or food availability.
Humans also exhibit instinctual behavior, although to a lesser extent than many other animals. For example, newborn infants exhibit innate reflexes such as rooting, sucking, and grasping. Some researchers also believe that certain aspects of human behavior, such as language acquisition and social bonding, may have an innate or instinctual component.

Answer:
True.
Explanation:
It is true that biological levels of organization of living things arranged from the simplest to most complex are:
organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.What is biological level of organization?Levels of organization are natural systems that are frequently described by part-whole connections, with higher ones being made up of lower levels. The atomic, molecular, cellular, tissue, organ, organismal, group, population, community, ecosystem, landscape, and biosphere levels of organization are common in the literature.What is cell?The smallest unit in biology that can exist on its own and makes up all living creatures and bodily tissues.

All of the following are characteristics of proteins EXCEPT:
A They contain genetic information
B They can catalyze chemical reactions.
c They can transport materials.
D They can repair tissues.
Answers
Answer: A.
Explanation: Proteins are made by decoding genetic information carried by DNA, but contain no genetic information themselves. Although the sequence of amino-acids in a protein matches the code in DNA, there is no process for using protein as a template for DNA.
Proteins may be structural, like collagen in tendons or keratin in hair and fingernails, or enzymes active in metabolism, or in transport, such as haemoglobin that transports oxygen, or in transporting ions into and out of cells against a concentration gradient.

Their bonds are mentioned as follows:
Adenosine (A) is paired with thymine (T) Cytosine (C) is paired with guanine (G)However, the base thymine (T) is present only in the nucleotide of DNA and the base uracil (U) is present only in the nucleotide of RNA.

How humans changed the balance of the park ecosystem
Answers
Answer:
Humans change ecosystems in many ways, such as habitat destruction, pollution, introduction of invasive species, and overexploitation of species.
The most common way that humans damage ecosystems is by destroying habitat. For example, we remove trees, change the flow of water, and change grasslands into farms. These practices can lead to local extinctions of species and cause other species to migrate to new areas.
