Answer:
vertebrate probably has more strength and support while the invertebrate probably has more soft and stuff.
Vertebrates are have well developed and long bones in legs and hands. Whereas, invertebrates have soft short and fragile bones and nerves in legs and hands.
What are vertebrates?Vertebrata, which means chordates with backbones, is the subphylum of animals that includes all types of animals. The majority of the Chordata, phylum, are vertebrates.
Underneath skin and muscle is where the vertebrate skeleton resides. The brain and spinal cord are enclosed by the skull and vertebral bones, while the heart and other internal organs are shielded by the ribs. The interior core of the legs is made up of long bones.
Exoskeletal material covers almost all exterior features on vertebrates, as well as a few internal ones. These structures include the body, legs, fore and hind digestive tracts, some respiratory surfaces, eyes, mouthparts, antennae, and antennae.
Invertebrates have no vertebral column and are have not developed bones or muscles inside. Insects, mollusks, cnidarians etc. belongs to this class. Their legs have no muscle tissues and long vertical bones.

Which best describes the relationship between chromosomes, genes, and inherited traits?
A Genes and chromosomes both carry DNA that determine inherited traits from parents to offspring.
B Genes are located within chromosomes. Genes determine the passing and expression of inherited traits from parent to offspring.
C Chromosomes are located within genes. Chromosomes determine genetic code for inherited traits from parent to offspring.
D Genes are controlled by chromosomes. Chromosomes create mutations and new genes that are passed from parent to offspring.
Answers
Genes are located within the chromosomes. Genes determine the passing and expression of the inherited traits from parents to the offspring. Thus, the correct option is B.
What are Genes?Gene is the basic unit of heredity and the molecular gene in the nucleus is a sequence of nucleotides in the form of DNA, which undergoes transcription to produce a functional RNA. The molecular genes are of two types: protein-coding genes and noncoding genes. The protein-coding gene undergoes translation to produce functional proteins from RNA.
Chromosomes are present on the DNA molecule which contain the genes. Genes determine the expression of traits in an organism and are transmitted from the parents to their offspring.
Therefore, the correct option is B.

A group of scientists wanted to investigate how populations of organisms can change over time. They decided to study a population of birds on the Galapagos Islands exposed to extreme conditions of drought.
Which of the following would be the best hypothesis to test how the birds might adapt to these conditions over time?
A.Birds exposed to extreme drought will become less attractive over time.
B.Extreme drought conditions could cause bird species to become extinct.
C.If birds are exposed to extreme drought then their beak size will quickly change overnight.
D.Birds might breed with other species and adapt to these conditions.
Answers
Answer:
I Dont think it would be D. Breeding with other species is possible, but extremely rare. I Think its most likely C, because C shows an adaptation, their beak changing in size. They might be changing so that their beaks are strong enough to break through plants or ground and drink the water from it. There might also be other reasons, that is just my prediction. If it gets too harsh, however, there might not be a way to adapt to it and they may go extinct. But as i said i think it would be C.

Why might dew form in the morning:
○The temperature fell overnight, and colder air can hold less water vapor.
Hope this helped you- have a good day bro cya)
Dew form in the morning because the temperature fell overnight, and colder air can hold less water vapor. The correct option is c.
What is dew?As the temperature drops and things get colder, dew forms. The air around an object will cool if it becomes cold enough. Warm air can store more water vapor than cold air, but not as much. As a result, the air around cooling objects is forced to condense water vapor.
At the night, the temperature is less because of not sun. In less temperature, water freezes, and the air consensus turns into drops of water.
Water tends to gather on surfaces and draw itself together as droplets, or dew, since it has high surface tension. It frequently gathers in locations that are naturally chilly.
Therefore, the correct option is c, The temperature fell overnight, and colder air can hold less water vapor.

In plants, there is a conducting tissue that is located in the veins. Inside, there are xylem cells that conduct water and minerals upward from roots to leaves and phloem that conducts food. Plants have only water solutions flowing through the tubing. Animals can have one of two kinds of circulatory systems: open or closed. In animals, each blood vessel in the network is responsible for transporting nutrients and oxygen to cells and for removing wastes and carbon dioxide from cells.
