Q. How is the sex of the child determined in human beings ?
Please answer dis also..thanks!
➜ In human beings, sex of the child depends upon which kind of male gamete fertilise the female gamete. If sperm carrying X chromosome fertilises the ovum carrying X chromosome, then the child born will be a girl. If a sperm carrying Y chromosome fertilises the ovum which carries X chromosome, then the child born will be a boy.

Based on the information given, state ONE way the bag or its contents will have changed by the next day. Support your answer with an explanation. *
Answer:
The size of the bag will shrink due to movement of water molecules out of the bag into the beakerdue to osmosis.
Explanation:
The difference in concentration between two regions results in a phenomenon known as diffusion.
Diffusionnis the process by which molecules of a substance move from regions of higher concentration to regions of lower concentration until equilibrium concentration is reached by the two regions. Water molecules moves across regions of different concentration through a semipermeable membrane in a special form of diffusion known as osmosis.
Osmosis refers to the movement of water molecules from regions of high concentration (dilute solutions ) to regions of low concentration (concentrated solutions ) through a semipermeable membrane until equilibrium is attained.
The solution in the bag is less concentrated than the solution innthe beaker. The bag serves as a semipermeable membrane allowing water molecules to move out of it into the beaker due to the difference in concentration of the two solutions. As a result, the size of the bag shrinks while the level of the solution in the beaker rises as it becomes less concentrated.

Many tree frog populations are threatened due to habitat loss. In an effort to promote conservation, tree frogs may be bred in captivity. A zoo acquired male and female tree frogs from two different populations. In the zoo, the tree frogs were able to successfully mate within their own population, but breeding attempts between the two populations were unsuccessful. Based on this information, which statement correctly describes the relationship between the two populations of tree frogs?
this is for biology test pleasee someone help
Answer: Same Genus but different species
Explanation: took the test and came back
The statement which correctly describes the relationship between the two populations of tree frogs is same genus but different species.
What are the characteristics of genus?A genus is a class or group of something. In biology, it's a taxonomic group covering more than one species. This is a term used by biologists to classify more than one species under a larger umbrella.
A species is defined as a group of organisms made up of similar individuals capable of interbreeding or exchanging genes. Genus: A genus is a taxonomic classification that includes closely related species.
Genus is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family.

Answer: The question is not complete, here is the completed part gotten from other website.
Mammals and turtles are more closely related than are lungfishes and sharks. Hagfishes, lungfishes, and frogs have lobed fins.
Lancelets and coelacanths are more closely related than are chimaeras and coelacanths.
Organism (a) is a common ancestor of all chordates.
Descendants of organism (d) have limbs with digits. birds and ray-finned fishes have a notochord and jaws.
rays and frogs have vertebrae. organism (c) is a common ancestor of lampreys and lungfishes?
The correct options are;
Mammals and turtles are more closely related than are lungfishes and sharks.
Descendants of organism (d) have legs.
Rays and frogs have a vertebral column.
-Birds and ray-finned fishes have a notochord and jaws
Explanation:
This is because phylogenetic tree is a branching diagram that entails different evolutionary relationships that occur between organisms or biological species having common decent or ancestors and showing similar and differences in their genetic characteristics or traits. It shows how species evolved from their ancestors.
How will photosynthesis and respiration keep you alive, and what do you need to do?
Explanation:
While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis (Figure below) and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels.

a. sleep b. breathing c. memory d. pain transmission
Answer:
c. memory
Explanation:
Memory is not a function of the reticular formation. Sleeping, breathing, and pain transmission all are the functions of reticular formation. Thus, the correct option is C.
What is reticular formation?
Reticular formation is a part of the pons region of brain which controls the sleep-wake cycle and also filters stimuli to separate out relevant background stimuli from irrelevant ones.
Reticular formation is one of the phylogenetically earliest parts of the brain and it is crucial for controlling some fundamental processes such as sleeping, breathing, and pain transmission.
The reticular formation is an essential process for the numerous activities of the brainstem. It is located strategically amid the significant nuclei in the brain cells and the nerve fibers that traverse it. The reticular formation looks like an intricate web network.
Therefore, the correct option is C.
