Answer:
Insects
Explanation:
Insects, like ants, have three body sections, the head, thorax, and abdomen. They have three pairs of legs, three on each side of the body, six legs. And some ants have wings.
The arthropods with three body sections, three pairs of legs, and one or two pairs of wings are the insects.
What are the characteristics of arthropods?Arthropods are invertebrate animals with an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda.
Insects such as ants, dragonflies, and bees. Arachnids such as spiders and scorpions. Myriapods (a term which means “many feet”) such as centipedes and milipedes. Crustaceans such as crabs, lobsters, and shrimp.
All arthropods posses an exoskeleton, bi-lateral symmetry, jointed appendages, segmented bodies, and specialized appendages. The major arthropod classes can be separated by comparing their number of body regions, legs, and antennae.

Give an example of how a biome is an open system from the point of view of the biosphere, atmosphere, lithosphere, and hydrosphere.
Answers
Given what we know, we can confirm that the biome is in fact an open system due to the interactions between the biosphere, atmosphere, lithosphere, and hydrosphere.
What is the biome?The biome is the collection of air, soil, water, and all the organisms that reside within these ecosystems. In order to describe an open system, we say that the system must have external interactions. A biome is an open system because it has both internal and external interactions, such as with asteroids in space. The internal interactions include the ones between the biosphere, atmosphere, lithosphere, and hydrosphere.A prime example is the movement of water through each of the spheres.Therefore, since each part of the biome interacts with each other as well as with external sources such as space, we can confirm that it complies with the definition of an open system.

FILL IN THE BLANK put in simple terms, the intrinsic muscles of the hand are classified anatomically as the group at the base of the thumb (the______group), those found at the base of the little finger (the _______group), and everything in between (the ___group).
Answers
To put it simply, the intrinsic hand muscles are divided anatomically into the Thenar group, which is located at the base of the thumb, the Hypothenar Group, which is situated at the base of the small finger, and everyone in between .
The intrinsic hand is made up of four muscular groups. These are the lumbrical, interossei, thenar, and hypothenar muscles. The intrinsic muscles, including the lumbricals & interosseus muscles, balance finger movement during normal hand function and produce this broad sweeping motion. They are also in charge of connecting the extension of the interphalangeal joints (IP) with the flexion of the metacarpophalangeal joint (MCP). The carpal & metacarpal bones serve as the origin & insertion points for the intrinsic hand muscles. The forearm is frequently the origin of the extrinsic hand muscles, which enter into hand . The majority of the hand's intrinsic muscles, including all seven interossei, three hypothenar muscle fibres, the adductor hanced, the deep heads of the FPB, and the two flexors longus, are innervated by the ulnar nerve.

Where in the plant are the hormones auxins produced? (Select all that apply.)
A. stems
B. roots
C. chloroplasts
D. seeds
E. leaves
F. fruits
Answers
Answer:
Stems and root
Explanation:
Auxins facilitate stem elongation while inhibiting axillary bud formation, ensuring apical dominance. The root, branches, and stem and tip all contain them. Hydroxy Acetic Acid is a perfect example. Auxin is indeed a growth hormone that facilitates cell elongation and is formed in the stem tip.
In stems, roots, leaves and fruits, hormones auxins are produced. Therefore, the correct options are A,B,E and F.
Plants' apical meristems are where auxins are predominantly made, and they are then carried by the plant's vascular system. Although there are synthetic auxins available for agricultural use, indole-3-acetic acid (IAA) is the predominant naturally occurring auxin in plants. Auxins are crucial hormones for plant growth and development, to sum up. They control a variety of tropic responses as well as cell elongation, apical dominance, root growth, phototropism, fruit development, and leaf abscission. Gaining knowledge of auxin regulation and function can help us better understand plant biology.
Therefore, the correct options are A,B,E and F.

Along the slanting, horizontal line there are five dots labeled from left to right as: 1, 2, 3, 4, and 5. There is one vertical line between each of the consecutive five dots. The lines are labeled from left to right as Perch, Frog, Pigeon, Rats, and Human. A text box below the branching tree diagram is labeled Derived Shared Characteristics. In the box it says from left to right Terrestrial during all stages, Jaws, Walking on two legs, Mammary glands and hair, and Four limbs.
Look at the possible derived shared characteristics, shown in the text box. Think about where these should be placed along the branching tree diagram. Where in the branching tree would you most likely write "lives on land during all life stages"? Explain your answer.
Answers
"The derived shared characteristic 'Terrestrial during all stages' should be placed at the base of the tree diagram."
SupThe characteristic "Terrestrial during all stages" is a shared characteristic among all five species being compared in the branching tree diagram. This means that it is a characteristic that all of these species have in common, and therefore it is likely that it was present in their common ancestor.
Since the base of the tree represents the common ancestor of the species being compared, it makes sense to place this characteristic at the base of the tree. This also helps to show that this characteristic is a defining trait of the group of species being compared and that it has been present in their lineage since their common ancestor.

Answers
Organelles carry out specific functions inside cells, whereas inclusions store glycogen, lipids, pigments, and other substances.
An organelle is a type of subcellular structure that, much like an organ in the body, is responsible for performing one or more specialised tasks within the context of the cell.
The nucleus, which is responsible for storing genetic information, the mitochondria, which are responsible for producing chemical energy, and the ribosomes, which are responsible for assembling proteins, are some of the more essential organelles found in cells.
An organelle is a particular structure that may be found inside of a cell, and there are a wide variety of distinct organelles. Within a cell, the structures known as organelles are also referred to as vesicles. And they truly do have a purpose that is crucial, because we need to compartmentalize all of the operations that are taking place within the cell.

Explain why there is currently an imbalance of Carbon in the atmosphere and what is causing it.
Answers
There is currently an imbalance of carbon in the atmosphere due to burning of fossil fuels, deforestation, and pollution and this causes global warming.
What is Carbon imbalance in atmosphere?
Burning of fossil fuels, changing the land use, and use of limestone to make concretes all are important for the transfer of significant quantities of carbon into the surrounding atmosphere. As a result, the amount of carbon dioxide gas in the atmosphere is rapidly rising and it is already greater than the concentration of carbon dioxide at any period of time in the last 3.6 million years.
By increasing the amount of the greenhouse gases such as carbon dioxide in the atmosphere, the Earth is becoming warmer with time. Carbon dioxide spends a long time, in the atmosphere before decomposition, so even if the people stopped adding carbon dioxide to the atmosphere now because, the Earth would continue to warm.

"While bird watching, Carl hypothesized he could identify 73 different types of birds in one day. He actually identified 65 different types of birds. What was his percent error
Answers
Answer:
15.87%
Explanation:
Carl's percentage error would be 15.87%.
From the data, the hypothesized number of birds Carl could identify is 73.
The actual number of birds he was able to identify is 63.
The margin of error between the two = 73 - 63 = 10.
Hence, percentage error = error/true measurement x 100%
= 10/63 x 100% = 15.87%

In animal cells, the actin cytoskeleton forms a cleavage furrow to physically separate the cellular contents during cytokinesis. Explain why this approach won't work in plant cells, and describe how they do it instead.
Answers
Answer:
The approach of cytokinesis to form cleavage furrows does not work for the plant cells due to specific reasons. These reasons are -
The presence of a rigid outermost layer called cell wall in plant cells that do not allow for forming furrows.
Centrioles present in animal cells helps in maintaining the organisation of mitotic spindle and completion of cytokinesis, however, not found in plant cells. The Golgi vesicles secrets and makes a septum or cell plate in the equatorial plane of the cell wall with the help of microtubules and phragmoplast help in the separation of two daughter cells.
The process of cytokinesis to form cleavage furrows does not function for the plant cells due to the following reasons :
The existence of a tough extreme layer called cell wall in plant cells that do not allow for forming furrows.Centrioles present in animal cells help in supporting the organisation of mitotic spindle and completion of cytokinesis, however, not found in plant cells.What is a cleavage furrow It is formed when animal cells separate?Cleavage furrow is a constriction formed by the actin ring during animal-cell cytokinesis that leads to cytoplasmic division. cytokinesis is the division of the cytoplasm the following mitosis to form two daughter cells.
