Answer: Insects
Explanation:
The Arthropoda is the largest phylum in the animal kingdom because about 85 percent of all known species are arthropods, and insects alone make up about 75 percent of known species.
Arthropods are divided into the following classes:
- Crustaceans
- Insects
- Arachnids
- Myriapods
Thus, insects contains the greatest number of species
Answer: Insects.
Explanation:
Insects are largest group of invertebrates animal. They belong to phylum arthropoda and the are about 1 million or more. Insects have a pair of antenna, their body is cover with exoskeleton, they have three pairs of leg, their body is divided Into head , thorax and abdomen. Their eyes are bulged. They have pairs of wings. Examples are ants, bees, termites, flies, butterfly, grasshopper e.t.c.
c. biotechnology.
b. agriscience
d. transportation.
compaction and cementation
deposition and compaction
erosion and weathering
The two parts of sedimentary rock formation that include the breakdown and carrying away of existing rock are erosion and weathering. Thus, the correct option for this question is D.
Weathering may be defined as a type of process through which a large rock is gradually broken down into smaller fragments by the action of water, wind, roots of plants, etc. Weathering is of two types:
When the process of weathering may be terminated, the activity of erosion may have occurred. This activity is also carried out by factors like water air, overgrazing of cattle, human activities like deforestation, etc. The main effect of soil erosion is to remove the topsoil which is extremely fertile in nature.
Therefore, erosion and weathering are the two parts of sedimentary rock formation that include the breakdown and carrying away of existing rock. Thus, the correct option for this question is D.

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.

Bacterial Population
Time
Which of these most likely explains why the bacterial population stopped growing?
The bacteria mutated from photosynthetic to carnivorous organisms and consumed one another until all the individuals were dead.
The bacteria reproduced in the system but eventually died due to limited resources
The bacteria became diseased and were unable to survive in the closed system
The bacteria competed for nutrients and died after all the nutrients were consumed
The statement that most likely explains the stop of bacterial populations to grow is the bacteria competed for nutrients and died after all the nutrients were consumed.
Bacterial growth may be defined as the proliferation of bacterium into two daughter cells, in a process called binary fission.
When there are enough nutrients in the petri dish, a rapid increase is shown in the graph, but during the course of time when nutrients become limited, it affects the growth of the bacterial population.
Therefore, the statement that most likely explains the stop of bacterial populations to grow is the bacteria competed for nutrients and died after all the nutrients were consumed.

B - The bacteria competed for nutrients and died after all the nutrients were consumed
Answer:
We can see those planets because there in between the sun and the earth, that's why we can see them, also we can see mars because it is close to earth.
Explanation:
transports water and minerals
transports food
produces food through photosynthesis
Vascular tissues can provide support to the plants and also help in the transport of water, mineral and food. So, the correct options are A, B and C.
Vascular tissues mainly perform the function of supplying all the parts of the plant with water, minerals and food. there are two kinds of vascular tissues - xylem and phloem.
Xylem is the water-conducting vascular tissue. It conducts water from the roots of the plant to various other parts. In the xylem, the movement of water is unidirectional, which means it only conducts water from bottom to top and sometimes sideways
Phloem is the food-conducting vascular tissue of plants. It conducts water from leaves to other parts of the plant. In phloem, the movement of water is bidirectional, which means it conducts water from both directions. Xylem and phloem lie next to each other in a bundle called a vascular bundle.
Lycophytes are a group of seedless vascular plants which have a unique arrangement of their vascular tissues. In these plants, the lycophytes support the growth of plants.
Therefore, the correct options are A, B and C.

Answer:
Explanation:
Xylem transports and stores water and water-soluble nutrients in vascular plants.
Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.
Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant.
