Biology is a natural science that studies living organisms and their interactions with their environment. Living organisms are organized in a complex hierarchy and share key properties. Through time, less-diverse ancestral organisms evolved into the diverse life forms we see today.
Biology is the science that studies living organisms and their interactions with one another and their environments. This discipline attempts to describe and understand the nature of the universe in parts or as a whole. Biology is considered a natural science along with fields related to the physical world and its phenomena.
Living organisms share several key properties such as order, sensitivity or response to stimuli, reproduction, growth and development, regulation, homeostasis, and energy processing. They are organized in a hierarchy that includes atoms, molecules, organelles, cells, tissues, organs, and organ systems. Organisms, in turn, are grouped as populations, communities, ecosystems, and the biosphere.
This is further evidenced in a diagram called a phylogenetic tree that can be used to show evolutionary relationships among organisms. This indicates that the diversity of life today has evolved from less-diverse ancestral organisms over billions of years.

Answer: yes
Explanation: because they all connect
B. carbon
C. hydrogen
D. oxygen
Answer:
Carbon atoms B.
Explanation:
The atoms of an organic molecule are typically organized around chains of carbon atoms. Inorganic compounds make up 1%–1.5% of a living cell's mass. They are small, simple compounds that play important roles in the cell, although they do not form cell structures
Answer: The shrimp population would decrease.
Explanation:
Answer: tooth comb
Explanation: Strepsirhines are any member of the clade (a group of animals or other organisms derived from a common ancestor species) Strepsirrhini, one of the two suborders (a taxonomic category below order and above infraorder) of primates. They have a special lower incisor called a tooth comb which consists of long, flat teeth with microscopic grooves, and used for grooming the fur.
Strepsirhines, a suborder of primates that includes lemurs and lorises, have a distinct structure called a toothcomb, made up of closely packed lower incisors that stick out from the mouth. Apart from other unique features like a grooming claw, this toothcomb sets strepsirhines apart from other primates.
Strepsirhines, a suborder of primates that includes lemurs and lorises, have unique anatomical features that set them apart from other primates. They have incisors in their lower jaw that are packed closely together and stick out from the mouth in a structure called a toothcomb. This toothcomb, in combination with a clawlike second toe known as a grooming claw, is a hallmark of strepsirhines. The toothcomb is used for grooming - removing debris and parasites from their fur - and is also thought to assist in feeding.
Unlike the majority of mammals, which are diphyodonts and have two sets of teeth in their lifetime, strepsirhines' teeth do not necessarily get replaced. Strepsirhines are found primarily in the 'Old World' - parts of Africa, Asia, and Europe - though a number of species are indigenous to islands such as Madagascar.

Answer: Activates glycolysis and inhibits gluconeogenesis
Explanation:
Fructose‑2,6‑bisphosphate coordinates glucose breakdown in glycolysis generates by modulating the action of phosphofructokinase 1 and at the same time inhibits gluconeogenesis.
