Select the Nuclear membrane closeup. How is the nuclear membrane similar to the cell membrane? Select the Nuclear membrane closeup. How is the nuclear membrane similar to the cell membrane?
Answers
Answer:
A nuclear membrane is a double membrane that encloses the cell nucleus. It serves to separate the chromosomes from the rest of the cell. The nuclear membrane includes an array of small holes or pores that permit the passage of certain materials, such as nucleic acids and proteins, between the nucleus and cytoplasm.
The similarities between nuclear membrane and cell membrane are both are made up of lipid bilayers, main functions of both membranes are protection and transportation, both are extremely important for the cell survival.
What is nuclear membrane?"The nuclear membrane is a double layer that encloses the cell's nucleus, where the chromosomes reside."
What is the other function of nuclear membrane?"The critical function of the nuclear membrane is to act as a barrier that separates the contents of the nucleus from the cytoplasm."
What is cell membrane?"The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment."
What are the other functions of cell membrane?The other functions of the cell membrane include
identification,communication,regulation of solute exchange through the membrane,isolation of the cytoplasm from the external environment.What is lipid bilayers?"The lipid bilayer (or phospholipid bilayer) is a thin polar membrane made of two layers of lipid molecules."

James is researching the advantages of varying beak sizes of four bird species in a local habitat. He records and graphs the data to show how many individuals there are in each species with different sizes of beak. The graph is provided. If all four species of birds are transported to a new habitat with completely new food sources, which species will most likely be able to avoid extinction?
Answers
The specie will avoid extinction which have a large amount of food in that environment probably specie B.
Specie that avoid extinctionThat specie will most likely be able to avoid extinction which receives more amount of desired food because food is the main source on which all living organism can survive.
If desired food is not available for the organism, its population size decreases and reaches to the point of extinction so we can conclude that the specie will avoid extinction which have a large amount of food in that environment.

Answers
Answer:
Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell. Indeed, apart from random mutations, each successive duplicate cell will have the same genetic composition as its parent, due to the inheritance of the same chromosome set and similar biological environment. This works well for replacing damaged tissue or for growth and expansion from an embryonic state. Because the genes contained in the duplicate chromosomes are transferred to each successive cellular generation, all mitotic progeny are genetically similar. However, there are exceptions. For example, there are genetic variations that arise in clonal species, such as bacteria, due to spontaneous mutations during mitotic division. Furthermore, chromosomes are sometimes replicated multiple times without any accompanying cell division. This occurs in the cells of Drosophila larvae salivary glands, for example, where there is a high metabolic demand. The chromosomes there are called polytene chromosomes, and they are extremely large compared to chromosomes in other Drosophila cells. These chromosomes replicate by undergoing the initial phases of mitosis without any cytokinesis (Figure 2). Therefore, the same cell contains thick arrangements of duplicate chromosomes side by side, which look like strands of very thick rope. Scientists believe that these chromosomes are hyper-replicated to allow for the rapid and copious production of certain proteins that help larval growth and metamorphosis

How does the shape of an algae cell help it function?
Answers
Answer: Microtubules provide a rigid structure, or cytoskeleton. or produce oxygen and consume carbon dioxide
Explanation:
Most cells contain microtubules, which are tubelike structures formed by tubulin proteins. Microtubules appear and disappear as needed in many algae.
What are microtubules?Microtubules are important cytoskeleton components. They are found in all eukaryotic cells and play roles in mitosis, cell motility, intracellular transport, and cell shape maintenance.
Microtubules are made up of alpha- and beta-tubulin subunits that have been assembled into linear protofilaments.
Microtubules, along with intermediate filaments and microfilaments, are components of the cell skeleton that determine cell shape.
Microtubules play a variety of roles, including mitotic spindle assembly in dividing cells and axon extension in neurons.
Microtubules, which are tubelike structures formed by tubulin proteins, are found in the majority of cells. In many algae, microtubules appear and disappear as needed.
Microtubules provide a rigid structure, or cytoskeleton, in the cell that aids in cell shape determination and maintenance, especially in species lacking cell walls.
Thus, this way, the shape of an algae cell help it function.

Explain development of pollen grains and ovules
Answers
Explanation:
Pollen is produced within the anthers (microsporangia or pollen sacs) of the flower. During its development from an undifferentiated mound of cells (anther primordium) the anther forms two general groups of cells. The reproductive or sporogenous cells give rise to the microspores and are formed from cells located centrally within the developing anther. The non-reproductive cells form discrete anther tissues layers and include the epidermal, cortical and tapetal cell layers surrounding the sporogenous cells. The tapetum which is the innermost layer of the pollen sac plays a dominant role particularly during the microspore stage. For example, many male sterile mutations affect tapetal cell functions and development is often arrested during the microspore stage.
Microsporogenesis and microgametogenesis
Two distinct and successive developmental phases, microsporogenesis and microgametogenesis, lead to the production of the mature microgametophytes.
dev
Microsporogenesis comprises the events which lead to the formation of the haploid unicellular microspores. During microsporogenesis the diploid sporogenous cells differentiate as microsporocytes (pollen mother cells or meiocytes) which divide by meiosis to form four haploid microspores. Each diploid meiocyte gives rise to a tetrad of four haploid microspores and microsporogenesis is complete with the formation of distinct single-celled haploid microspores.
Microgametogenesis comprises events which lead to the progressive development of the unicellular microspores into mature microgametophytes containing the gametes. This phase begins with the expansion of the microspore which is commonly associated with the formation of a single large vacuole. Vacuolation is accompanied by the displacement of the microspore nucleus to an eccentric position against the microspore wall. In this position the nucleus undergoes first pollen mitosis (pollen mitosis I) which results in the formation of two unequal cells, a large vegetative cell and a small generative cell each containing a haploid nucleus. The generative cell subsequently detaches from the pollen grain wall and is engulfed by the vegetative cell forming a unique 'cell within a cell' structure. The engulfed generative cell divides once more by mitosis (pollen mitosis II) to form the two sperm cells completely enclosed within the vegetative cell cytoplasm either before pollen is shed (tricellular pollen) or within the pollen tube (bicellular
