Questions for Plant Cell Mitosis 1 How many chromosomes are in an onion cell 2 How many daughter cells are produced from each mitotic cell division 3 How many total chromosomes does each daughter cell have 4 Which phase of the cell cycle did you see most often in the onion root tip

A population of bacteria is treated with an antibiotic Because of variation in the population of bacteria what is a possible outcome of the treatment The population will be better able to obtain a food source C D A B All of the bacteria will be resistant to the antibiotic Some of the bacteria may be resistant to the antibiotic and survive The population will increase rapidly

Which of the following is an advantage of sexual reproduction O A It allows for variation within a population O B C OD It generates identical offspring in a population It allows several offspring to be produced in a short period of time It allows organisms to not depend on other organisms to reproduc

Sperm are much smaller than eggs Why Check all likely explanations 1 Sperm need only provide DNA whereas eggs must provide cytoplasm proteins and mitochondria for the embryo 2 Sperm contain only half the DNA of an egg 3 Smaller sperm were selected because they could swim faster and reach the egg first 4 Sperm seem smaller because they are long and thin but they actually contain an equal amount of cytoplasm 5 Sperm are small to avoid being recognized by the female s immune system

Slime molds and Entamoebas belong to Amoebozoa Supergroup Even though they are under the same category they differ in their mode of nutrition and life cycle Use the diagram of the slime mold life cycle to identify what these two organisms share 8 Amoebas aggregate into a structure called a slug 7 New haploid amoebas are released 00 Meiosis 6 Zygote grows and undergoes meiosis and multiple rounds of mitosis Haploid and Asexual Reproduction fusion 2n Fertilization 10 Migration stops and the aggregate forms a fruiting body at the end of a stalk 9 Slug migrates at a rate of 2 mm per hour 5 Two amoebas fuse to form a zygote nucleus 4 Germination gives rise to amoeba which divide to form more individual cells plasmodium mature spores Spore germinates 1 Mature fruiting body generates spores Meiosis 2 Mature fruiting body releases spores Both amoeba and slime mold have amoeboid cells involved in reproduction O Both amoeba and slime mold produce spores Both amoeba and slime mold ingest pre formed organic molecules O Both amoeba and slime mold produce fruiting bodies

7 AKS 8a Which of the following is the BEST reason an individual who agrees with therapeutic cloning for he purposes of study and therapy might cite to support their argument A Therapeutic cloning places an altered human cell in a woman s uterus In contrast reproductive cloning takes place in a laboratory and cannot lead to a human being B Therapeutic cloning holds great promise to alleviate human suffering and advance human knowledge C The processes for therapeutic cloning and reproductive cloning both share a fundamental act of destroying a human embryo a potential life D The embryos used in therapeutic cloning research are babies with functional organs

uterine cycles 2 Cycle Ovarian Uterine PRE OVULATION OVULAT POST OVULATION ION In a table given below mention what happens in each phase of the ovarian and uterine cycle both in pre ovulation and post ovulation 4 3 Sharks typically reproduce sexually A particular female shark however gave birth in a zoo despite having no recent contact with a male shark 10 a Identify the type of cell division that produces eggs and sperm in animals such as sharks b Female sharks can store sperm after mating and then wait to fertilize their eggs Scientists investigated whether the female shark in the zoo did this Describe how DNA analysis can determine if the shark reproduced using stored sperm or if she reproduced asexually Be sure to include the source s of DNA being analyzed and the results of the analysis in your answer

the offspring and the parents are genetically 4 the new plants possess the combined genes 21 The diagram below represents some stages in the pro 1 Stage 2 represents a cell that CO 3 8 1 contains half the genetic material of an adul 2 shows clear evidence of tissue differentiation

X 2 bud shown in the diagram below was proda

The term semelparity a refers to an organism with a Type I survivorship curve O b best describes an organism who only produces offspring twice during th lifetime Oc best describes an organism who repeatedly produces offspring over the course of their lifetime d best describes an organism who only produces offspring once in their lifetime

The sperm of frog population A cannot fertilize the eggs of frog population B because the receptors on the egg for the arriving sperm do not recognize it. Thus these two closely related species of frogs cannot produce offspring. The isolating mechanism is: A prezygotic B. postzygotic C. temporal/chronological D. alopatric

While studying meiosis and mitosis for her genetics test, Marisa made notes of the kinds of cells produced from these processes with examples from the body. Which pairing of the cell produced during meiosis and example is correct? A) haploid cell: egg cell B) haploid cell: hair cell C) diploid cell: sperm cell D) diploid cell: liver cell

Which statement is factual? Asexual reproduction produces offspring that are identical to the parent. Sexual reproduction allows for diploid gametes to combine to increase genetic variation. Asexual reproduction leads to the formation of haploid gametes. Sexual reproduction does not require the production of gametes.

7. Which of the following is the common feature of asexual reproduction patterns observed in living things? A) Formation of individuals with different gene combinations B) Formation of two new individuals when replication is complete C) Division of the cytoplasm by node Occur with bud development E) Its basis is based on ONA mapping

E - Which evidence best supports the claim that jellyfish reproduce? 1. Jellyfish can make more jellyfish to continue their species. This is done with female jellyfish making eggs and then releasing the eggs when mature, at the same time male jellyfish will fertilize the eggs floating by. 2. Jellyfish babies are called "planulae". Soon the free-floating planulae will sink to the bottom of the ocean and attach on a hard surface, like a rock. They will develop tentacles and become a polyp and then soon a medusa, which is an adult jellyfish. 3. Jellyfish use their tentacles to obtain their food. If something swims by, it could get caught by the stinging cells on jellyfish. The jellyfish will then bring their food up to their mouths to ingest it. Why is your chosen evidence the best evidence for reproduction as a characteristic of life: R- Which reasoning supports the claim that jellyfish are living? 1. Jellyfish are alive because the evidence supports the claim. 2. The reason why jellyfish are alive is because they have all of the characteristics of life and to be considered living, organisms must have all characteristics. 3. The jellyfish eating is the jellyfish obtaining and using energy which is a characteristic of life and if a thing has at least one characteristic of life, it must be living.
